Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for easily recognizing an updated part in an updated drawing when the drawing is updated by making additions, modifications, or the like to, for example, architectural drawings. A drawing creation system.

[0002]

2. Description of the Related Art Conventionally, for example, architectural drawings and the like created by a drawing creator A are distributed to respective workers B, and each worker B performs a predetermined operation according to the distributed drawings. It has become.

[0003] Therefore, if the drawing creator A updates the drawing by partially changing the drawing with respect to the drawing already distributed to the worker B, the worker B is renewed. The drawings will be distributed. In response to this, the worker B compares the previously distributed drawing with the updated drawing, or notifies the worker B of the change by the drawing creator A, and so on. The person B recognizes the changed portion or the changed content.

[0004]

However, in the above-mentioned method, the worker B who receives the updated drawing recognizes the changed portion by comparing the drawing before updating with the drawing after updating. Since the worker B does not know where the change has been made, the whole drawing is compared with the whole drawing to detect the changed portion. As the drawing becomes larger and the drawing becomes finer, It takes time to detect. In addition, there is a problem that an overlook of a changed portion occurs.

[0005] Further, a method is conceivable in which the drawing creator A notifies the worker B of the changed drawing from the drawing before the update by clearly stating the changed part from the drawing before the update. As a result, even if the worker B is notified of the changed portion, the worker B cannot recognize the state of the changed portion before the update unless the drawing is compared with the drawing before the update. Further, it is conceivable that the drawing creator A verbally gives the explanation to the worker B, but there is a problem that the time between the drawing creator A and the worker B is restricted.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a drawing creating system which can easily recognize a changed portion in an updated drawing. .

[0007]

To achieve the above object, a drawing creation system according to a first aspect of the present invention provides a drawing creation system which updates drawing data at a time earlier than one time in a drawing which is appropriately updated. Data storage means for storing the drawing data at the one point in time and display means for superimposing and displaying the drawing data at the one time point and the drawing data stored in the storage area. A display form of data, a display form of the drawing data stored in the storage area, a display form of a place where the drawing data at the one time and the drawing data stored in the storage area are redundantly displayed, Are superimposed and displayed in different display forms.

According to the present invention, the drawing data at a time point before the one time point is stored in the predetermined storage area, and the drawing data at the one time point and the drawing data at the time point before this time are superimposed. Is displayed. That is, for example, if the updated drawing data is the drawing data at one time, the drawing data before updating is stored in a predetermined storage area, and the drawing data before updating and the drawing data after updating are superimposed. Is displayed. At this time, the display mode of the drawing data at one time, the display mode of the drawing data stored in the storage area, and the drawing data at the one time and the drawing data stored in the storage area were displayed in an overlapping manner. Location, for example, on a line segment of one drawing data,
The display form of the part where the line segment of the other drawing data is displayed in an overlapping manner is superimposed and displayed in a different display form.

Therefore, the drawing data before the update is displayed in the first display form, and the drawing data after the update is displayed in the second display form. The first and second display modes are set so as to be displayed in the third display mode, and the positions of the reference point on the XY plane of each drawing in the drawing before update and the drawing after update match. Then, when the pre-updated and post-updated drawings are superimposed and displayed, a portion that has not been changed is displayed at the same position, so that this portion is displayed redundantly. In other words, a portion that has not been changed is displayed in the third display format, a portion deleted by the update does not exist in the updated drawing, and thus is displayed in the first display format, and a portion added by the update is updated. Since it does not exist in the previous drawing, it is displayed in the second display mode. Therefore, by referring to the display form of each part of the drawing, the changed part can be easily recognized.

[0010] Further, a drawing creation system according to claim 2 of the present invention is characterized in that the display form is a display color. According to the present invention, since the display color is changed and displayed, for example, when the display is performed by a plotter or the like, the drawing data at one point is drawn in magenta as the updated drawing data. And
If drawing data at a time before one time is drawn as cyan as drawing data before updating,
When these drawing data are superimposed and drawn on the plotter paper, cyan and magenta are displayed in the drawing data that have not been changed in an overlapping manner. The added portion is displayed in magenta, and the portion deleted by updating is displayed in cyan. Therefore, by referring to the display color of each part of the drawing, the changed part can be easily visually recognized.

[0011]

Embodiments of the present invention will be described below. FIG. 1 is a schematic configuration diagram showing an example of a CAD system to which a drawing creation system according to the present invention is applied.

The CAD system 100 includes, for example, an input device 1 for inputting graphics, a display device 2 such as a graphic display, an output device 3 such as an XY plotter capable of performing color drawing, and a CAD processing program. A program storage device 4 for storing files consisting of drawing data such as CAD drawings created by CAD, an arithmetic processing device 6 connected to these devices by a bus or the like, Consists of

The arithmetic processing unit 6 reads the CAD processing program stored in the program storage device 4, executes a predetermined process based on the CAD processing program, and executes the input data input from the input device 1. The CAD drawing is created on the basis of the CAD drawing, the CAD drawing is displayed on the display device 2, and the created CAD drawing is output to the output device 3 based on an instruction from the input device 1. Further, a CAD drawing file having a designated file name is created for the created CAD drawing, and stored in the drawing file storage device 5.

When a CAD drawing is to be changed, another file consisting of the drawing data of the CAD drawing before updating is formed, and this file is stored in the drawing file storage device 5 as a CAD drawing file (storage area) before updating. Update the CAD drawing and transfer the updated CAD drawing data to CA.
Update and store in D drawing file.

On the other hand, when drawing an updated CAD drawing, the drawing data updated and stored in the CAD drawing file is drawn to the output device 3 in a color set in advance as a display form, for example, cyan (blue-green). Then, the drawing data stored in the pre-update CAD drawing file is displayed on the same sheet, and the updated drawing is drawn in a color (in this case, a color different from cyan) such as magenta. An instruction is given to draw in (reddish purple) (display means). At this time, for example, a portion where the updated CAD drawing and the updated CAD drawing are overlapped, such as a portion where the line segment of the updated CAD drawing is overlapped with a line segment of the updated CAD drawing. Display color and CAD before update
A drawing color in which the display color of the drawing and the display color of the updated CAD drawing are different from each other is set as the drawing color of the CAD drawing before updating and the drawing color of the updated CAD drawing, respectively. Therefore, in this case, the updated CAD
The drawing color of the drawing is cyan, the drawing color of the CAD drawing before updating is magenta, and the display color of a portion where these are drawn in duplicate is a blackish color (hereinafter referred to as black), which are different display colors.

Next, the operation of the above embodiment will be described with reference to the flowcharts of FIGS. For example, when updating a CAD drawing consisting of a floor plan of a house as shown in FIG. 4, first, drawing data of the CAD drawing consisting of this floor plan is read from a CAD drawing file stored in the drawing file storage device 5. Read (step S1). Then, the read drawing data is used as a pre-update CAD drawing file.
It is stored in the drawing file storage device 5 (step S2, data storage means).

Then, by executing the CAD processing program stored in the program storage device 4, the CAD drawing is changed and, as shown in FIG. 5, for example, the smaller Japanese-style room and the kitchen are changed to LDK. Then, the closet of the Western-style room is changed to the closet, the larger Japanese-style room is changed to the Western-style room, and a getter box is installed at the entrance (Step S3). When the drawing is changed, the reference position on the XY plane of the CAD drawing is not changed.

Then, the drawing data of the changed CAD drawing is updated and stored in the original CAD drawing file (step S4). As a result, the drawing file storage device 5 stores the drawing data of the updated CAD drawing, that is, the CAD drawing file including the drawing data of FIG.
The drawing data of the D drawing, that is, the pre-update CAD drawing file including the drawing data of FIG. 4 is stored.

Subsequently, when the CAD drawing updated in this manner is drawn by the output unit 3, the arithmetic processing unit 6 first sets the C drawing as shown in the flowchart of FIG.
The output device 3 is instructed to draw the drawing data of the AD drawing file in magenta (step S1).
1).

In response to this, the output device 3 is operated, and CA
Drawing is performed based on the drawing data of the D drawing file, that is, the drawing data of the updated CAD drawing. As a result, FIG.
Is displayed in magenta.

Subsequently, in the arithmetic processing unit 6, the updated C
For the same paper on which the AD drawing is drawn, the CAD before update
Like drawing the drawing data of the drawing file in cyan,
An instruction is given to the output device 3 (step S12).

In response to this, the output device 3 is operated, and the drawing data of the CAD drawing file before updating, that is, the C data before updating is output.
Drawing is performed based on the drawing data of the AD drawing. Thereby, the CAD drawing before update shown in FIG. 4 is displayed in cyan.

Therefore, the CAD drawing before updating shown in FIG. 4 and the CAD drawing after updating shown in FIG. 5 are superimposed and displayed on the paper after drawing as shown in FIG. At this time, before and after updating, X-
Since the reference position of the Y plane is not changed, the two CAD drawings are drawn on the same XY plane, the CAD drawing before updating is drawn in cyan, and the CAD drawing after updating is drawn in magenta. Therefore, a portion where these are overlapped and drawn is displayed in black. In other words, the portions drawn in duplicate, that is, the portions displayed in black (represented by solid lines in FIG. 6) represent the portions where no change has been made.

Also, a portion displayed in magenta (in FIG. 6, it is represented by a dashed line, and characters are surrounded by a dashed line).
Indicates that it does not exist in the CAD drawing before the update, and indicates a portion newly added by the update, and a portion displayed in cyan (indicated by a broken line in FIG. 6, characters are enclosed by a broken line). ) Does not exist in the updated CAD drawing, and thus represents a portion deleted by the update.

Therefore, C before and after updating shown in FIG.
By referring to the display color in a drawing drawn by superimposing the AD drawing, it is possible to easily recognize the changed portion and the state before and after the change.

In addition to changing the drawing colors of the drawing data before and after updating, when drawing the drawing data before and after updating, the display colors of the drawing data before updating and
The drawing colors of the drawing data before and after the update are changed so that the display color of the drawing data after the update and the display color of the portion where the drawing data before the update and the drawing data after the update are overlapped are different from each other. Since the setting is made, by referring to a sheet of paper on which the drawing data before and after the update are superimposed and drawn, the changed portion and the unchanged portion are clearly shown. be able to. In particular, since magenta and cyan are set as the drawing colors, the portions where these are overlapped are displayed in black, and the display colors are clearly different, so that they can be easily identified.

Therefore, for example, even if the drawing creator A changes the CAD drawing after the CAD drawing before updating is already distributed to the worker B, as shown in FIG. If the drawing in which the subsequent CAD drawing is superimposed and displayed is distributed to the worker B, the worker B
Can be easily recognized by referring to the drawings, and the changed color, the state before and after the change can be easily recognized from the display color of each color. In particular, since the display is performed in each color, it is possible to easily detect visually, and accordingly, it is possible to prevent omission of detection of a changed portion.

By the way, the processing time required for detecting a changed portion is reduced by about 90% as compared with a case where a changed portion is detected by comparing a conventional CAD drawing before updating and a CAD drawing after updating. I was able to confirm that I could do it.

Further, since CAD drawings before and after updating are displayed on one sheet, it is easy to recognize from which state and how to change without comparing the two drawings. be able to.

Further, since the drawing creator A only needs to make changes to the CAD drawing irrespective of the conventional method, the burden on the worker B can be reduced without increasing the processing burden on the drawing creator A. And the processing time required to detect the changed portion can be reduced.

In the above embodiment, a case has been described in which a CAD drawing before updating is drawn in magenta, and a CAD drawing after updating is drawn in cyan. , And the CAD drawing before updating may be drawn in cyan.

The drawing colors are not limited to cyan and magenta, but may be any color arrangement that can clearly distinguish the display color and the two display colors when two colors are drawn in an overlapping manner. If applicable. Also, a case has been described in which the image is drawn in different colors as the display mode.
In the case of drawings where each line type has no meaning,
For example, the CAD drawings before and after the update may be displayed by changing the line type, such as a thick broken line and a thin line, or the line type and the display color may be combined and drawn. In short, the present invention can be applied to any display form that can clearly identify a portion drawn by each display form alone and a part drawn by duplication in the two display forms.

Also, in the above embodiment, a case has been described in which two CAD drawings before and after updating are displayed in a superimposed manner. For example, three CAD drawings of the first to third editions are used. It is also possible to draw three or more CAD drawings in a superimposed manner. In this case, the drawing data of the drawings in each edition is individually stored, and each of the editions and each of the overlappingly displayed images are displayed. This can be realized by setting a display mode and rendering the display mode, which is different for each location.

In the above embodiment, the CAD
In the case where the drawing is changed, the case where the reference position on the XY plane of the CAD drawing is not moved has been described. However, when the reference position on the XY plane is moved at the time of the change. For example, when drawing by the output device 3, the reference positions of the two CAD drawings may be matched.

Further, in the above-described embodiment, a case has been described in which a CAD drawing composed of a floor plan of a house is changed. Can be.

In the above embodiment, the CAD
Every time a drawing is updated, the pre-update drawing data is updated to the pre-update CA
A case has been described in which a CAD drawing before and after updating is superimposed and displayed as a D drawing file. For example, when drawing data of a CAD drawing is read from a CAD drawing file, this drawing data is read. Only when instructed to save as a pre-update CAD file, save this as a pre-update CAD drawing file, and when outputting a drawing by the output device 3, only when instructed to superimpose, The drawing data of the CAD drawing file at this time and the CAD drawing file before updating may be superimposed and drawn.

By doing so, for example, the second
Save the drawing data of the drawing in the version as a CAD drawing file before update, and then make several revisions,
When outputting the drawing data in the sixth edition, it is possible to superimpose the drawing in the second edition and the drawing in the sixth edition by designating the superimposed display. Therefore, the present invention can be applied to a case where, for example, the drawings in the second edition are distributed to the worker B after the drawings in the second edition are repeatedly updated and the drawings in the sixth edition are distributed to the worker B.

Further, in the above embodiment, the portion described as "push-in" in FIG. 4 is changed to "closet" in FIG. 5, and when these are superimposed and displayed, these two characters are displayed. When changing the drawing, the “closet” is replaced by the “push-in” of the drawing before updating because it is displayed overlapping
Although it is described so that it is shifted from the description part of
In general, there is no problem even if figures such as lines are displayed in an overlapped manner, but if characters are displayed in an overlapped manner, it is difficult to read the figures.
When transmitting to the output device 3, for the characters, the display information of the characters in the drawing data before the update and the drawing data after the update are compared, and for the characters whose display positions overlap, the characters in the drawing data before the update are compared. If the display position is corrected to a position where characters do not overlap, or if the characters before updating are not displayed, so that different characters do not overlap each other in the two drawings, the contents of the character change will be clearly indicated This allows the user to more clearly recognize the changed contents of the characters.

In the above embodiment, the CAD
A case has been described in which, when drawing data of a drawing file is read, a pre-update CAD drawing file is created based on the read drawing data. After the drawing is updated, the drawing data is updated and stored in the CAD drawing file. At this time, the drawing data stored in the CAD drawing file may be transferred to the pre-update CAD drawing file.

Regardless of when the drawing data is read from the CAD drawing file, for example, the user is instructed to save the drawing data while changing the drawing data while referring to the display screen of the display device 2. When
A new storage C consisting of the drawing data at this point
By forming an AD drawing file and storing it, the drawing data at a desired time may be stored.

Similarly, the drawing data of the CAD drawing file is read out and output and displayed on the output device 3. However, when superimposed display is instructed when the drawing data is changed, the change at this time is performed. By superimposing and displaying the inside drawing data and the stored drawing data, the drawing data at the desired time and the stored drawing data may be displayed in a superimposed manner.

In the above embodiment, the case where the XY plotter or the like is applied as the output device 3 has been described. However, a printer or the like can be applied. Also, the case where the drawing data is output to the output device 3 has been described, but it is also possible to superimpose and display the drawing data on an output device such as a CRT display capable of color printing. The drawing data is associated with R (red), G (green), and B (blue), respectively,
What is necessary is just to write in RAM.

[0043]

As described above, according to the first aspect of the present invention,
According to the drawing creation system according to the above, the drawing data at a time point before the one time point of the drawing to be updated as appropriate is stored, and the drawing data at the one time point and the stored drawing data are superimposed and displayed. At this time, the display form of the drawing data at one point in time, the display form of the saved drawing data, and the display form of the place where these drawing data are displayed in duplicate are different from each other. Since the display form is superimposed, it is easy to detect a change between the drawing data at one point in time and the saved drawing data at an earlier point in time by referring to the display form at each point. Can be.

According to the drawing creation system of the second aspect of the present invention, the display color of the drawing data at one point in time, the display color of the saved drawing data at an earlier point in time, Since the display color of the location where the drawing data is duplicated is displayed differently, the changed location can be easily detected visually by referring to the display color of each location. it can.
