(Configuration and work flow of information processing device)
First, the configuration of the information processing apparatus and the flow of work for creating a 3D model using the information processing apparatus and adding attribute information to the 3D model will be described with reference to FIGS.

  FIG. 1 is a block diagram of a CAD apparatus. In the figure, reference numeral 101 denotes an internal storage device, and 102 denotes an external storage device, which includes a semiconductor storage device such as a RAM for storing CAD data and CAD programs, a magnetic storage device, and the like.

  Reference numeral 103 denotes a CPU device, which executes processing in accordance with a CAD program command.

  Reference numeral 104 denotes a display device that displays a shape and the like in accordance with a command from the CPU device 103.

  Reference numeral 105 denotes an input device such as a mouse or a keyboard that gives instructions to the CAD program.

  Reference numeral 106 denotes an output device such as a printer that outputs a paper drawing or the like in accordance with a command from the CPU device 103.

  Reference numeral 107 denotes an external connection device that connects the CAD device and an external device, supplies data from the device to the external device, and controls the device from an external device.

  FIG. 2 is a flowchart showing the processing operation of the CAD apparatus shown in FIG.

  First, when an operator instructs to start a CAD program with the input device 105, the CAD program stored in the external storage device 102 is read into the internal storage device 101, and the CAD program is executed on the CPU device 103 (step). S301).

  The operator interactively instructs the input device 105 to generate a shape model on the internal storage device 101 and display it as an image on the display device 104 (step S302). This shape model will be described later. Note that when the operator designates a file name or the like with the input device 105, the shape model already created on the external storage device 102 can be read into the internal storage device 101 so that it can be handled on the CAD program.

  The operator creates an attribute placement plane, which is a virtual plane for placing attribute information such as dimensions and notes, in the three-dimensional space in which the shape model is created, using the input device 105 (step S303). The setting of the attribute arrangement plane will be described later. In order to easily determine the position of this attribute arrangement plane, it is displayed on the display device as image information such as a frame (double frame, fill in frame). The attribute placement plane setting information is stored in the internal storage device 101 in association with the shape model.

  Moreover, it is desirable to give a name to the attribute arrangement plane created as necessary. The name given to the attribute arrangement plane can be displayed at a predetermined position on the frame of the attribute arrangement plane as a name label. The setting of the name label will be described later.

  The operator adds a dimensional tolerance or the like as attribute information to the shape model using the input device 105 (step S304). The added attribute information can be displayed on the display device as image information such as a label. The added attribute information is stored in the internal storage device 101 in association with the shape model.

  The operator associates the attribute information with the attribute arrangement plane by using the input device 105 (step S305). The attribute information and the related information on the attribute arrangement plane are stored in the internal storage device 101. An operator may designate an attribute arrangement plane in advance and perform attribute assignment while associating it with the attribute arrangement plane. Further, the operator can set / cancel the association of the attribute information with the attribute arrangement plane using the input device 105.

  Next, the operator designates the attribute arrangement plane by using the input device 105 to display / hide the attribute information such as the attribute arrangement plane and the dimension tolerance associated with the attribute arrangement plane, or display control such as coloring. This is performed (step S306).

  In addition, when the operator creates an attribute arrangement plane using the input device 105, the viewpoint position, line-of-sight direction, and magnification of the attribute arrangement plane are set. By setting this attribute arrangement plane display information and specifying this attribute arrangement plane, the shape model can be displayed with the set viewpoint position, line-of-sight direction, and magnification. Further, since the attribute arrangement plane and the attribute information are associated with each other, the attribute information associated with the designated attribute arrangement plane can be selectively displayed. The attribute arrangement plane display information is stored in the internal storage device 101.

  The attribute information can be stored in the external storage device 102 or the like according to the operator's instruction (step S307).

  An identifier can be added to the attribute information, and this identifier can be added and stored in the external storage device 102. Using this identifier, attribute data can be associated with other data.

  The attribute information on the external storage device 102 added with information can be read into the internal storage device 101 to update the attribute information.

  The operator uses the input device 105 to store the CAD attribute model in which the attribute placement plane position information, the attribute placement plane display information, and the attribute information are added to the shape model in the external storage device 102 (step S308).

(Input and display of attribute information to the 3D model)
Further, input of attribute information to the 3D model, creation method of the attribute arrangement plane, and display of the 3D model to which the attribute information is added will be described in detail.

  3 to 7 are diagrams illustrating the 3D model, the attribute information, and the attribute arrangement plane. FIGS. 8 to 10 are flowcharts illustrating processing operations when adding the attribute arrangement plane and the attribute information to the 3D model. .

  In step S121 of FIG. 8, the 3D model 1 shown in FIG. 3 is created, and in step S122, a necessary attribute arrangement plane is set.

Attribute Placement Plane Here, the attribute placement plane defines requirements related to the display of the 3D model 1 and the attribute information added to the 3D model 1.

  In the present invention, the attribute arrangement plane is defined by the position of one point (viewpoint, hereinafter referred to as viewpoint) in the (virtual) three-dimensional space, the normal direction (viewing direction) of the plane to be created, and the 3D model 1, In addition, it is assumed that information of display magnification (hereinafter simply referred to as magnification) of the attribute information added to the 3D model 1 is also included.

  Here, the line-of-sight position is defined as a position where the 3D model 1 in the line-of-sight direction can be seen, that is, displayed. For example, the attribute arrangement plane 212 is set at a position of 60 mm from the outer shape of the front surface 201 of the 3D model 1 (FIG. 3).

  However, here, as for projection views (front view, plan view, left and right side views, bottom view, and rear view) by so-called trigonometry, any position as long as the line-of-sight position is located outside the 3D model 1 is used. But it doesn't matter what is displayed.

  Further, the position of the viewpoint is a point that coincides with the display center of the display device 104 when displaying the 3D model 1 and the attribute information added to the 3D model 1.

  Next, the normal direction is made to coincide with the visual line direction when displaying the 3D model 1 and the attribute information added to the 3D model 1 from the viewpoint position.

  The magnification is a magnification for enlarging when a 3D model shape in a (virtual) three-dimensional space is displayed on the display device 104.

  The viewpoint position, line-of-sight direction, and magnification, which are parameters of the attribute arrangement plane, can be changed at any time.

  For example, in FIG. 3, an attribute arrangement plane 211 is defined in which the direction from the outside to the inside of the 3D model is the line-of-sight direction and is orthogonal to the plane 201a of the plan view shown in FIG. The viewpoint position and the magnification are determined so that almost all of the shape of the 3D model 1 and the attribute information to be added can be displayed on the display screen of the display device 104. For example, in the present embodiment, the magnification is 1 and the viewpoint position 201f is determined at substantially the center of the plane 201a of the plan view (in FIG. 3, the two-dot chain line 201d is an approximate outline of the front view as the attribute arrangement plane 211). Shows the projected state). Similarly, a line-of-sight attribute arrangement plane 212 orthogonal to the front view surface 201c and a line-of-sight attribute arrangement plane 213 orthogonal to the side view surface 201b are also set.

  In order to clearly indicate the position of each attribute arrangement plane, the attribute arrangement plane is represented by a square double frame. In this embodiment, a frame is used as a means for clearly indicating the position of the attribute arrangement plane. However, the present invention is not limited to this. The shape may be a polygon other than a square or a circle.

  As described above, it is possible to set and display the name label indicating the name of the attribute arrangement plane in the frame of the attribute arrangement plane. Here, an example of setting / changing / displaying the name label will be described. To do.

  FIG. 24 is an explanatory diagram showing a state in which the name label is displayed on the frame set on the attribute arrangement plane. A name label 402 representing the name of the frame 401 is set and displayed on the frame 401 on the attribute arrangement plane. Reference numeral 403 denotes a 3D model. The name label 402 is displayed at a preset position on the attribute arrangement plane, but the display position, name label display size, color, font, and the like can be arbitrarily changed. Further, by determining the display position in advance, it is possible to obtain an effect that the coordinate system in which the attribute arrangement plane is arranged can be visually known from the display position of the display label.

  The naming method of the name label may be a front view, a plan view, etc., as well as a so-called trigonometric projection, or may be simply a symbol such as A, B, C, etc. It is better to decide the naming method for each type of cross-sectional view and partial detail view.

  In addition, in the case of cross-sectional views, partial detail views, etc., when creating attribute placement planes, if they are automatically named according to a predetermined naming method, there is a problem that names overlap. It does not occur and the operator load is further reduced.

  Next, attribute information is input in association with each attribute arrangement plane set in step S122 (step S123). FIGS. 4, 6A and 7A are diagrams showing a state in which attribute information is given to the 3D model in association with the attribute arrangement planes 211, 212, and 213. FIG. FIGS. 5B, 6B, and 7B show the 3D model 1 and attribute information viewed from the viewpoint positions of the attribute placement planes 211, 212, and 213, respectively.

  The size of the attribute information (character or symbol height) associated with the attribute placement plane is changed according to the magnification of the attribute placement plane. The size (mm) of the attribute information is defined as the size in the virtual three-dimensional space where the 3D model exists (not the size when displayed on the display device 104).

  Further, the association between the attribute arrangement plane and the attribute information may be after the attribute information is input. For example, as shown in the flowchart of FIG. 9, a 3D model is created (step S131), attributes are input in step S132, and attribute information is associated with a desired attribute arrangement plane in step S133. Further, modification such as addition and deletion of attribute information associated with the attribute arrangement plane is performed as necessary.

  When the attribute information is associated with another attribute arrangement plane, the size of the attribute information is changed according to the magnification of the change destination attribute arrangement plane.

  The attribute information may be input in a state in which the 3D model 1 is displayed two-dimensionally by displaying from the line-of-sight direction defined by each attribute arrangement plane. The input can be realized without any change from the process of creating a two-dimensional drawing by so-called 2D-CAD. Moreover, you may input, displaying as three-dimensional as needed. Since the input can be performed while viewing the 3D model 1 three-dimensionally, it can be realized more efficiently and without mistakes.

  Next, description will be made on viewing attribute information of the 3D model 1. By selecting a desired attribute arrangement plane in step S141 in FIG. 10, the shape of the 3D model 1 and the attribute arrangement plane are associated with each other based on the viewpoint position, line-of-sight direction, and magnification of the attribute arrangement plane selected in step S142. The assigned attribute information is displayed. For example, when the attribute arrangement plane 211, the attribute arrangement plane 212, or the attribute arrangement plane 213 is selected, FIG. 5, FIG. 6B, or FIG. 7B is displayed. The attribute information is arranged so as to face the line-of-sight direction of each attribute arrangement plane. As a result, it can be seen in a two-dimensional manner on the display screen very easily and easily.

  Next, an example for easily selecting the attribute arrangement plane will be introduced. First, a method of displaying a frame of an attribute arrangement plane of a selectable 3D model and allowing an operator to select an attribute arrangement plane using an input device such as a pointing device such as a mouse (FIG. 3).

  Next, a method of displaying the names of selectable attribute arrangement planes in a list format and selecting from them (not shown) is also conceivable.

  Furthermore, it is also conceivable to select the image in the state viewed from the line-of-sight direction of the attribute arrangement plane (FIG. 5, (b) in FIG. 6, or (b) in FIG. 7) as an icon and select it. (FIG. 35).

(Other input methods for attribute information)
In the input of the attribute information, the attribute information is associated with each attribute arrangement plane. However, the association means is not limited to the above. For example, attribute information may be grouped and the group and the attribute arrangement plane may be associated with each other. Good.

  This will be described based on the flowcharts shown in FIGS.

  By selectively grouping attribute information input in advance or based on search results and associating the group with an arbitrary attribute arrangement plane, the same results and effects as described above can be obtained. Also, attribute information associated with the attribute placement plane can be manipulated by making modifications such as addition and deletion of attribute information to the group.

  That is, the 3D model 1 is generated (step S151), attribute information is input (step S152), and the viewpoint position, line-of-sight direction, and magnification of the attribute arrangement plane are set for the 3D model (step S153). The attribute information input in step S152 is grouped, and the set attribute arrangement plane and the grouped attribute information are set in association with each other (step S154).

  When performing display, as shown in FIG. 12, the attribute placement plane is selected (step S161), and the attribute information associated with the selected attribute placement plane is changed to the viewpoint position, line-of-sight direction, The information is displayed on the display device 104 according to the magnification information (step S162).

(Setting multiple attribute placement planes)
Next, a case where a plurality of attribute arrangement planes are set for the same line-of-sight direction will be described (a plurality of attribute arrangement planes are parallel to each other).

  FIG. 13 is a flowchart showing a processing operation when a plurality of attribute arrangement planes are set for the same line-of-sight direction, and FIG. 14 is a case where a plurality of attribute arrangement planes are set for the same line-of-sight direction. It is a figure which shows 3D model.

  In the 3D model 1 shown in FIG. 3, a case where a plurality of attribute arrangement planes are set so that the projection direction of the front view and the line-of-sight direction coincide with each other will be described.

  As described above, the 3D model 1 is created (step S171), and in step S172, the attribute placement plane 212 (viewpoint position, line-of-sight direction, magnification), which is the first attribute placement plane, is set. The line-of-sight direction of the attribute arrangement plane 212 is orthogonal to the plane 201c of the front view, the magnification is, for example, 1 time, and the viewpoint position is 30 mm from the front view outline, and is generally the center of the surface 201c of the front view.

  In step S173, attribute information as shown in (a) of FIG. 6 is input in association with the attribute arrangement plane 212. When viewed from the line-of-sight direction of the attribute arrangement plane 212, as shown in (b) of FIG. In addition, it can be seen very easily in two dimensions.

  Next, in step S174, the attribute placement plane 214 (viewpoint position, line-of-sight direction, magnification), which is the second attribute placement plane, is set. The line-of-sight direction of the attribute arrangement plane 214 is set to be parallel to the plane 201c of the front view, the magnification is, for example, 1 and the viewpoint position includes the center axis of the hole of the attribute arrangement plane 3D model.

  In the present description, the attribute arrangement plane 214 is represented by a rectangular fill shape (FIG. 14).

  At this time, the 3D model 1 viewed from the attribute arrangement plane 214 has a cross-sectional shape of the 3D model 1 cut by the virtual plane 214 as shown in FIG.

  Attribute information (for example, the hole size 12 ± 0.1 in FIG. 15B) is input in association with the attribute arrangement plane 214. When the attribute arrangement plane 214 is selected, the cross-sectional shape of the 3D model 1 and attribute information associated with the attribute arrangement plane are displayed.

  Further, if the 3D model 1 is moved, rotated, or the like, a three-dimensional display can be performed as shown in FIG.

  That is, when the attribute arrangement plane 214 is selected, the attribute information associated with the attribute arrangement plane existing in the same line-of-sight direction area as the 3D model existing in the line-of-sight direction of the attribute arrangement plane 214 is displayed, and the anti-gaze direction (see FIG. The 3D model shape and attribute information of the area are not displayed.

  According to the present embodiment, it is possible to handle not only attribute information relating to the outer shape but also attribute information relating to the cross-sectional shape in the same line-of-sight direction. As a result, the attribute information can be input and displayed while looking at the cross-sectional shape, so that the specified location of the attribute information can be easily and immediately understood.

  Moreover, it is good also as a structure which has two or more attribute arrangement | positioning planes in which the shape of 3D model 1 looks the same. FIG. 16 shows an attribute arrangement plane 215 and an attribute arrangement plane 216 having the same viewing direction. In this example, the attribute arrangement plane 215 and the attribute arrangement plane 216 are suitable for the plan view of the 3D model 1. For example, attribute information that is easier to see can be realized by grouping and associating attribute information with each attribute arrangement plane. For example, FIG. 17 is a plan view of the 3D model 1 in which attribute information related to external dimensions is grouped.

  FIG. 18 groups attribute information related to the hole position and hole shape in the above. The grouped attribute information is associated with the attribute arrangement plane 215 and the attribute arrangement plane 216, respectively. By grouping related attribute information in this way and assigning them to the attribute placement plane, the related attribute information becomes easier to see.

○ Position of attribute information In order to express the 3D model and attribute information to be added to the 3D model as a two-dimensional drawing on the display screen in an easy-to-understand manner, the operator selects or appropriately selects a plurality of attribute information of the part of the 3D model to be expressed or Group and associate with attribute placement plane. In the case of a two-dimensional drawing representation method, the position of the attribute information may be arranged in the line-of-sight region of the related attribute arrangement plane, but the so-called “3D drawing” in which attribute information is added to the 3D model and used as a drawing. In order to make full use of the merits of the 3D model, a device is required.

  One of the merits of 3D models is that they can be represented in three dimensions in a form close to the real thing on the display screen, so the operator who creates the model or the operator of the next process using that model (process designer, mold designer / producer) , A measurer, etc.) is the point that the 2D to 3D conversion work (this was mainly done in the operator's head), which is necessary when handling 2D diagrams, can be omitted. This conversion work often depends on the ability of the operator. In this conversion work, there is a possibility that forgery due to erroneous conversion or loss of conversion time may occur.

  In the 3D drawing, it is necessary to devise the display of the attribute information (the position of the attribute information) at the time of the three-dimensional display in order not to impair the three-dimensional expression that is a merit of the 3D model.

  The points to be devised will be described with reference to FIG.

  19A is a perspective view of the 3D model 2 used for explanation, FIG. 19B is a plan view of the 3D model 2, and FIG. 19C is an attribute information added to the 3D model 2 without devising. FIG. 19D is a perspective view illustrating the arrangement of the attribute information.

  First, in order to create a two-dimensional plan view for the 3D model 2, an attribute placement plane is created and attribute information is input. The attribute arrangement plane (not shown) for creating the plan view is set in the line-of-sight direction orthogonal to the surface 2a of the 3D model 2, and the state displayed from the viewpoint of this attribute arrangement plane is shown in FIG. (B).

  When the attribute information is input, if the arrangement planes of the plurality of attribute information are staggered as shown in FIG. 19C, the attribute information overlaps and it is difficult to determine the contents of the attribute information. Since it is difficult to see even with a small amount of attribute information as shown in FIG. 19C, it can be easily imagined that if the shape is more complicated, the attribute information is no longer useful information and can no longer hold as a drawing in a perspective state.

  However, by arranging the attribute information in the same plane as shown in FIG. 19D, the attribute information does not overlap each other, and the attribute is equivalent to the representation of the two-dimensional drawing (FIG. 19B). Information can be easily identified.

  In this way, in the drawing form (three-dimensional drawing) for adding attribute information to the 3D model, not only the two-dimensional drawing expression but also the three-dimensional model that is the merit of the 3D model, the attribute information Can be easily determined, and can be used as a three-dimensional drawing (3D drawing).

  In this example, the 3D model has a simple shape. However, when a 3D model having an actual more complicated shape is handled, it is necessary to set a plurality of attribute arrangement planes in the same line-of-sight direction.

  A plurality of attribute arrangement planes and attribute information associated therewith may be displayed at the same time, and then a desired attribute arrangement plane may be selected or attribute information may be selected.

  At this time, if the attribute information arrangement plane and the attribute arrangement plane are separated from each other, the relation between the attribute information and the attribute arrangement plane becomes difficult to understand, and there may be a case where the selection is made by mistake. In order to avoid this, the attribute information should be arranged on the same plane as the attribute arrangement plane in order to make the association easy to understand visually.

  Furthermore, when creating the attribute arrangement plane in the same gaze direction described with reference to FIG. 16, it is preferable to arrange a plurality of attribute arrangement planes in the same gaze direction apart from each other. When displaying multiple attribute placement planes and associated attribute information at the same time, if the attribute placement plane is created on the same plane, the attribute information placement plane will also be the same plane. Even when viewed obliquely, the attribute information overlaps and is difficult to see. In the first place, since there is a lot of attribute information when viewed from the same direction, the attribute information is divided into a plurality of attribute arrangement planes. When attribute information is displayed at the same time, it is inevitable that the attribute information overlaps.

  Even if it is difficult to see that it is difficult to see from the line-of-sight direction, it is effective to dispose the attribute arrangement planes in the same line-of-sight direction apart as a means for making it easy to determine the attribute information in a perspective state.

(magnification)
Further, by setting the magnification of the attribute arrangement plane to a desired magnification, it is possible to make a complicated shape or a detailed shape easier to see.

  FIG. 20 is a diagram illustrating a state in which a part of the 3D model 1 is enlarged and displayed. For example, as shown in FIG. 20 (a), by setting an attribute arrangement plane 217 for the 3D model 1 with the line-of-sight direction facing the plan view, the viewpoint position near the corner, and the magnification of 5 times, for example. The step-like shape and attribute information can be displayed in an extremely easy-to-understand manner (FIG. 20B).

  This embodiment is effective for 3D-CAD in general and further for 2D-CAD regardless of the hardware constituting the 3D-CAD apparatus or the method of configuring the 3D shape model.

Magnification and size of attribute information The size of attribute information (height of characters and symbols) associated with the attribute arrangement plane is changed according to the magnification of the attribute arrangement plane (FIG. 20B). .

  The size (mm) of the attribute information is defined as the size in the virtual three-dimensional space where the 3D model exists (not the size when displayed on the display device 104).

  For example, in the attribute arrangement plane 211 (magnification 1), the size of the attribute information is 3 mm. FIG. 20C shows an example in which the character height is displayed as 3 mm in the same manner on the attribute arrangement plane 217 (magnification 5).

  Since the attribute information associated with the attribute arrangement plane 217 is displayed at a display magnification of 5 times, its size is 15 mm.

  In FIGS. 20B and 20C, a square line indicates a displayable range on the display device 104.

  If the attribute information is arranged so that it does not overlap, the position of the 3D model and the attribute information will be separated, making it difficult to understand the relationship between the shape and the attribute information related thereto, and possibly causing misreading. Further, if there is a lot of attribute information to be displayed, not all the attribute information can be displayed on the display device 104, and the display range must be changed to view the attribute information outside the displayable range.

  Also, if the size of the character is not changed when it is desired to display it in a reduced size (magnification is less than 1), the display size of the attribute information on the display device 104 is reduced in the reduced diagram display state, and the content of the attribute information is reduced. Cannot be determined.

  Therefore, it is desirable to change the size of the attribute information according to the magnification in consideration of the time when the attribute information is displayed.

  Therefore, the magnification and the size of the attribute information should be approximately inversely related. As an example, when the magnification of the attribute arrangement plane 211 is 1 and the size of attribute information is 3, the size of attribute information related to the attribute arrangement plane 217 is 0.6 mm.

  As described above, the attribute information is associated with the attribute arrangement plane. However, in the 3D model having a complicated shape, there is naturally a lot of attribute information, and a large number of attribute arrangement planes to be associated are set.

  In particular, the attribute placement plane for showing the cross-sectional shape is often placed on the center axis of the hole, etc., and the attribute placement plane will be concentrated in places where there are many hole shapes close to each other, It is difficult to visually recognize on the display device the correspondence between the attribute arrangement plane and the shape element (in this case, the hole) of the 3D model, which attribute arrangement plane is arranged in which hole shape. obtain.

  In addition, when the 3D model has a fine shape, an attribute arrangement plane (a so-called partial detailed view) for enlarging and displaying a part of the 3D model may be set. It can be difficult to visually recognize the correspondence between the shape portion and the minute shape portion.

  Therefore, in the present invention, it is possible to associate the shape element of the 3D model with the attribute arrangement plane and highlight it on the display device.

  An example of the implementation method will be described below with reference to the drawings.

(Association of attribute placement plane and section shape element)
First, a method and an operation state of associating a cross-sectional shape element such as a hole shape with an attribute arrangement plane will be described with reference to FIGS.

  FIG. 25A is an external perspective view of the 3D model. The 3D model 501 is provided with holes 502a, 502b, 502c, and 502d. FIG. 25B is a diagram (so-called plan view) viewed from a direction orthogonal to the surface 503 of the 3D model 501. FIG. 26 is a diagram illustrating a state in which the attribute arrangement planes are arranged in the holes 502a to 502d of the 3D model 501, and the attribute arrangement planes 504a to 504d are arranged on the central axis of each hole.

  The association between the attribute arrangement plane and the shape element is performed in the same manner as the above-described method of associating the attribute information with the attribute arrangement plane. Specifically, after creating a 3D model and arranging an attribute arrangement plane, a shape element to be associated is selected and the attribute arrangement plane is designated.

  Through the above operation, the attribute arrangement plane and the shape element are associated with each other and stored in the internal storage device 101. Further, it can be stored in the external storage device 102 or the like according to an operator's instruction.

  Next, highlighting of shape elements will be described.

  When the operator selects any one of the attribute arrangement planes 504a to 504d from the input device, the shape element of the 3D model associated with the selected attribute arrangement plane is highlighted (highlighted). For example, when the attribute arrangement plane 504a is selected, the hole 502a is highlighted and the position where the attribute arrangement plane is arranged can be easily recognized visually. (See FIG. 27.) Note that the attribute arrangement plane selection method includes a method of directly inputting the name of the desired attribute arrangement plane from the input device, a method of selecting the attribute arrangement plane frame using a pointing device such as a mouse, This may be done by selecting from a list of attribute placement planes.

  In the present embodiment, the case of highlighting the cylindrical surface of the hole 504a has been described. However, the present invention is not limited to this, and for example, the edge line of the hole may be associated with the attribute arrangement plane and highlighted.

  When highlighting by associating not only 3D model shape elements but also attribute information added to the associated shape elements, auxiliary figures and labels for recognizing the setting position of the attribute placement plane , The visibility is further improved.

  Examples of associating auxiliary figures and labels will be described below.

  First, an example of an auxiliary figure will be described with reference to FIG.

  FIG. 28A is a diagram showing a state in which the center axis 502a1 of the hole 502a is displayed as an auxiliary graphic in addition to the highlighting shown in FIG. The central axis 502a1 may be drawn on the attribute arrangement plane and associated with a desired attribute arrangement plane (504a in this example). However, the attribute arrangement plane 504a is arranged on the central axis of the hole 502a. It is better to automatically recognize the fact that it is recognized and to display it when it is highlighted.

  Next, examples of labels will be described.

  FIG. 28B is a diagram showing a state in which the fact that the attribute placement plane is set on the central axis of the hole 502a is displayed as text information in addition to the highlighting shown in FIG. . A note (label) 502a2 is added to the hole 502a, and is displayed in association with the highlighting of the hole 502a by associating the note 502a2 with the attribute arrangement plane 504a. Further, as in the case of displaying the auxiliary figure described above, it is better to automatically display the auxiliary figure.

  It goes without saying that the effect is further increased by displaying the auxiliary graphic and the label together. In this case, it may be set so that the arrow of the note 502a2 points to the central axis 502a1.

  In the above-described embodiment, the shape element associated with the attribute arrangement plane has been described using the 3D model in a state of being visualized on the display screen. However, in the present invention, the shape element is in an invisible state on the display screen. Even in such a case, highlighting can be performed in the same manner as described above. This will be described below with reference to the drawings.

  FIG. 29A is a diagram illustrating a state in which the 3D model is displayed on the screen of the display device. The 3D model 505 is provided with holes 506a and 506b. The hole 506b is in an invisible position on the screen of the display device (in the present embodiment, a hidden line is displayed as a broken line in order to notify the presence). FIG. 29B is a view (so-called plan view) viewed from a direction orthogonal to the surface 507 of the 3D model 505. FIG. 30 is a diagram illustrating a state in which the attribute arrangement plane is arranged in the holes 506a and 506b of the 3D model 505. The attribute arrangement plane 508a is arranged on the center axis of the hole 506a, and the center of the hole 506b. An attribute arrangement plane 508b is arranged on the axis.

  FIG. 31 is a diagram showing a state in which the attribute arrangement plane 508b is selected and the attribute arrangement plane 508b is highlighted. By transparently displaying the associated shape elements as illustrated, the shape elements can be recognized even when the 3D model is displayed in a state where the shape elements are not directly visible. The method for associating the attribute arrangement plane with the shape element, the method for selecting the desired attribute arrangement plane, and the method for highlighting the shape element are the same as described above.

(Association of attribute placement plane and fine shape part)
Next, a method and an operation state for associating a fine shape on the 3D model with the attribute arrangement plane will be described with reference to FIGS. 32 to 34.

  FIG. 32 is a diagram illustrating a state in which the 3D model is displayed on the screen of the display device. The 3D model 511 is provided with a protrusion 512 which is a fine shape portion. FIG. 33A is a diagram showing a state in which the attribute arrangement plane 514 is arranged on the 3D model, and FIG. 33B is a state in which the attribute arrangement plane is displayed facing the display screen. FIG.

  As shown in (b) of FIG. 33, the attribute arrangement plane 514 is set to enlarge and display the protrusion 512 portion from a direction orthogonal to the surface 513 of the 3D model 511. Further, each surface forming the protrusion 512 is associated with the attribute arrangement plane 514. As an association method, for example, a desired plane may be selected from the input device 105 and an attribute arrangement plane to be associated may be designated.

  In the above configuration, when the attribute arrangement plane 514 is selected, the projection 512 is highlighted as shown in FIG.

  The method for associating the projection 512 with the attribute arrangement plane 514 and the method for selecting the attribute arrangement plane are the same as those described in the description of the association between the cross-sectional shape element and the attribute arrangement plane. Further, even when the protrusion shape is invisible on the screen of the display device, it is possible to highlight the same as described above.

  As described above, the attribute arrangement plane is set when a large number of attribute arrangement planes are set in close proximity by associating the attribute arrangement plane with the shape element of the 3D model and highlighting them on the display device. The position can be easily recognized. Further, even when a fine shape portion exists in the 3D model and an attribute arrangement plane (so-called partial detailed view) for enlarging and displaying the fine shape portion is set, an operation such as enlarging or reducing the 3D model is not performed. In addition, it is possible to easily recognize the correspondence with the attribute arrangement plane.

○ Multiple selection of attribute placement planes In the above-described embodiment, when displaying attribute information associated with an attribute placement plane, the number of attribute placement planes to be selected is only one, but in view of the object of the present invention, There is no problem even if multiple attribute placement planes are selected.

  However, when performing single selection of the attribute arrangement plane, the position of the viewpoint and the direction of the line of sight are unique, so there is only one display method on the display device, but there are multiple display methods when multiple selections are made. You have to devise. For example, when multiple selections are made, all attribute information associated with the selected attribute placement plane is displayed, and it is possible to select which attribute placement plane setting is used for the viewpoint position and line-of-sight direction. Can be considered.

  In addition, the display of the attribute information is devised so that the group can be easily identified by changing the color for each related attribute arrangement plane.

○ Setting the horizontal or vertical direction of the attribute placement plane In the present invention, only the viewpoint position, line-of-sight direction, and magnification are set for the attribute placement plane. There wasn't.

  In the two-dimensional drawing, as shown in FIG. 22, rules are provided for the arrangement of views (plan view, front view, side view) that can be seen from each viewing direction. This is a device for making it easy to understand the positional relationship from each line-of-sight direction in order to represent the real three-dimensional shape on a two-dimensional plane.

  On the other hand, in a 3D drawing form in which attribute information is attached to a 3D model, a two-dimensional representation viewed from a direction orthogonal to the external surface of the 3D model (FIGS. 5, 6B, 7) In addition to (b)), the 3D model can be rotated from this state, and three-dimensional expressions (FIGS. 4, 6A, 7A) viewed from an oblique direction are also possible.

  Therefore, in the 3D drawing form, when displaying a plan view, a front view, and a side view, the horizontal direction or the vertical direction of the attribute arrangement plane (this horizontal direction or vertical direction is assumed to match each direction of the display screen) ) Need not be specified separately. If the 3D model and the attribute information assigned to it can be expressed correctly, it can be said that all of (b), (c), and (d) shown in FIG. 19 are correct expressions. Furthermore, if the 3D model is rotated a little, the 3D model can be expressed in three dimensions, and the location of the entire 3D model where the current view is, and the location of the plan view and side view as seen from other viewing directions are also easy This is because there is no particular problem even if it is displayed without worrying about the positional relationship of each line-of-sight direction in the horizontal direction or the vertical direction of the attribute arrangement plane.

  However, in the 3D drawing form in which attribute information is added to the 3D model, not all operators who handle the 3D drawing are in an environment where the 3D model can be freely rotated and displayed. This is because there are workplaces where it is sufficient to save and view the 2D image information electronic data format displayed by each attribute arrangement plane without modifying the 3D drawing. There are also workplaces that can only respond to traditional paper drawings.

  If such a thing is assumed, the rule seen like a two-dimensional drawing must be applied to the display seen from each gaze direction.

  Therefore, when creating the attribute arrangement plane, it is necessary to set a horizontal direction or a vertical direction when displayed on the display device 104.

  FIG. 36 shows a flowchart of the processing.

  First, a 3D model is created (step S181).

  Next, the viewpoint position, line-of-sight direction, and magnification are set for the 3D model, and an attribute arrangement plane is created (step S182).

  Then, the horizontal direction (or vertical direction) of this attribute arrangement plane is designated (step S183). In order to specify the horizontal direction (or vertical direction), the direction of three axes (X, Y, Z) existing in the (virtual) 3D space may be selected, the direction of the edge of the 3D model, It is also possible to select the vertical direction of the surface.

  By specifying the horizontal direction (or vertical direction) of the attribute arrangement plane, the display position of the 3D model and the attribute information displayed by selecting the attribute arrangement plane is uniquely determined.

  When creating another attribute arrangement plane, the horizontal direction (or vertical direction) may be specified while maintaining the relationship with the line-of-sight direction of the already created attribute arrangement plane.

○ Display method of attribute information In the above embodiment, the attribute placement plane is first selected as the order in which the attribute information input to the 3D model is selectively displayed, and then the attribute associated with the attribute placement plane is displayed. The explanation was given in the order of displaying information as appropriate. However, the present invention is not limited to this method. The attribute information is selected, and then the viewpoint position on the attribute arrangement plane to which the attribute information is associated. It is also effective to display the 3D model and the attribute information with the viewing direction and magnification.

  FIG. 37 (displayed from selecting attribute information) is a flowchart showing this series of processing operations.

  With the 3D model and attribute information in the plan view of FIG. 4 displayed, the hole diameter φ12 ± 0.2 is selected (step S311).

  This attribute information displays the 3D drawing and attribute information associated with the attribute arrangement plane 211 based on the viewpoint position, line-of-sight direction, and magnification set in the associated attribute arrangement plane 211 (step S312). ). In this case, a front view is displayed as shown in FIG.

  Thereby, since the relationship between the selected attribute information and the 3D model is displayed two-dimensionally, it becomes easier to recognize.

Surface selection method In the above embodiment, the attribute placement plane or attribute information is selected first as the order in which the attribute information input to the 3D model is selectively displayed, and then the attribute placement plane or attribute is selected. The method of appropriately displaying the attribute information associated with the attribute arrangement plane based on the setting of the attribute arrangement plane associated with the information has been described. However, the method is not limited to this method, and the 3D model geometry is not limited to this method. Select the information (Geometry), display the attribute information associated with the geometric information, and further the 3D model and the attribute by the viewpoint position, line-of-sight direction, and magnification of the attribute placement plane with which the attribute information is associated A method for displaying information is also effective.

  FIG. 38 (display from attribute information selection) is a flowchart showing this series of processing operations.

  The geometric information (ridge line, surface, vertex) of the 3D model is selected (step S321). The attribute information associated with the selected geometric information is displayed (step S322).

  If there is a plurality of associated attribute information, all of them may be displayed. Further, all attribute information belonging to the attribute arrangement plane with which the attribute information is associated may be displayed.

  Next, the 3D model and attribute information are displayed based on the viewpoint position, line-of-sight direction, and magnification (horizontal direction of the attribute arrangement plane) related to the displayed attribute information (step S323). At this time, if a plurality of attribute arrangement planes are candidates, the operator selects a target to be displayed.

  In this way, it is very easy to use because the related attribute information can be searched and displayed using the geometry of the 3D model as a key.

(Display and use of 3D model with attribute information)
Here, how to display and use the 3D model to which the attribute information created as described above is added will be described.

  The 3D model to which the attribute information created by the information processing device shown in FIG. 1 is added can be obtained by transferring the data of the created device itself or the 3D model created via the external connection device, to the other similar items. The information processing apparatus can be used in each process.

  First, the product / unit / part design engineer who created the 3D model, or the operator who is the design designer himself, creates the 3D model himself / herself, as shown in FIGS. 5, 6B, 7B. By performing the display as shown in Fig. 5, new attribute information can be added to the 3D model as if a two-dimensional drawing was created. Also, for example, when the shape is complicated, the desired attribute information can be efficiently and accurately displayed by displaying the 3D model alternately in 3D and 2D or on the same screen as necessary. Can be entered.

  Also, an operator in a position to check / approve the created 3D model displays the created 3D model in the same screen or by switching the display shown in FIGS. 5, 6 (b), and 7 (b). As a result, a check is performed, and mark, symbol, or attribute information such as coloring is added, which means checked, OK, NG, hold, examination required, or the like. It goes without saying that a check is performed while comparing and referring to a plurality of products / units / parts as necessary.

  Further, it can be used when a design engineer or design designer other than the creator of the created 3D model designs other products / units / parts by referring to the created 3D model. By referring to this 3D model, the creator's intention or design method can be easily understood.

  Further, when a 3D model is manufactured and manufactured, an operator who gives information necessary for the 3D model or attribute information can be used. In this case, the operator is an engineer who sets the production process of the product / unit / part. The operator adds, for example, instructions on the type of machining process, tools to be used, etc., or corners R and chamfers on ridges, corners, corners, etc. necessary for machining to the 3D model. Alternatively, a measurement method instruction with respect to dimensions, dimension tolerances, etc., addition of measurement points to the 3D model, information to be taken into account in measurement, etc. are input. As shown in FIGS. 5 and 6B and 7B, it is possible to efficiently and reliably observe the display that is arranged and created in an easy-to-read manner and confirm the shape three-dimensionally as necessary. Done.

  In producing and manufacturing a 3D model, an operator who obtains information necessary for making a desired preparation from the 3D model or attribute information can be used. In this case, the operator is a design engineer who designs dies, jigs, various devices, etc. necessary for production and manufacture. The operator understands and grasps the shape while viewing the 3D model in a three-dimensional state, and displays the necessary attribute information in an easy-to-see layout as shown in FIGS. 5, 6 (b), and 7 (b). Check and extract. Based on the attribute information, the operator designs a mold, a tool, various devices, and the like. For example, if the operator is a mold design engineer, the operator designs from the 3D model and attribute information while examining the mold configuration and structure. If necessary, corners R and chamfers are added to ridges, corners, corners, and the like necessary for mold production. When the mold is a resin injection mold, the operator adds a draft necessary for molding to the 3D model, for example.

  It can also be used by operators who produce and manufacture products / units / parts. In this case, the operator is a product / unit / part processing engineer or assembly engineer. The operator can easily understand and grasp the shape to be processed or assembled while viewing the 3D model in a three-dimensional state, as shown in FIGS. 5, 6 (b), and 7 (b). Processing and assembly are performed by looking at the created display. Then, if necessary, the operator checks the shape of the processing part and the assembly part. Further, the processed, difficult to process, or the processing result may be added as attribute information to the 3D model or already added attribute information, and the information may be fed back to the design engineer.

  Further, it can be used by an operator who inspects, measures, and evaluates a manufactured / manufactured product / unit / part. In this case, the operator is an engineer who inspects, measures, and evaluates a product / unit / part. The operator displays the measurement method, measurement points, and information to be careful of the measurement for the above dimensions, dimensional tolerances, etc. as shown in FIG. 5, FIG. 6 (b) and FIG. 7 (b). While confirming and checking the shape three-dimensionally as necessary, it is obtained efficiently and reliably, and inspection, measurement, and evaluation are executed. Then, the operator can give inspection, measurement, and evaluation as attribute information to the 3D model as necessary. For example, a measurement result corresponding to the dimension is given. In addition, a mark or a symbol or the like is given to the attribute information of a defective portion such as a dimensional tolerance or a defect, or a 3D model. Further, in the same manner as the check result, inspection, measurement, evaluated marks, symbols, coloring, or the like may be performed.

  Further, it can be used by operators in various departments and roles related to production / manufacture of products / units / parts. In this case, the operator creates, for example, a person in charge of manufacturing and manufacturing cost analysis, a person in charge of ordering a product / unit / part itself, various related parts, a product / unit / part manual, a packing material, and the like. The person in charge, etc. In this case as well, the operator can easily understand and grasp the shape of the product / unit / part while viewing the 3D model in a three-dimensional state as shown in FIGS. 5, 6 (b), and 7 (b). Perform various tasks efficiently by looking at the displayed layout.

[Other embodiments]

However, the present invention is not limited to this, and the attribute arrangement planes associated with each other may be highlighted by selecting a shape element.

  Further, the example of changing the color of the shape element and displaying the highlight method has been described, but the present invention is not limited to this, and any method can be used as long as the operator can easily recognize the shape element. For example, in the highlight display of the fine shape portion, the fine shape portion may be enlarged and displayed.
