Description

  The present invention relates to a drawing processing program used to create a drawing, a recording medium recording the drawing processing program, a drawing processing method, and a drawing processing system.

  CAD (Computer Aided Design) devices have become widespread, and various drawings can be easily created and used. Drawing using such a CAD apparatus is performed by inputting data by a designer or a CAD operator. This data input is generally performed by designating a specific line (two-dimensional) on the display screen and inputting a so-called vector value such as the direction and length of the line to be newly drawn. In some cases, a start point is determined using a cursor, and a line segment is created from the start point to the end point.

  In such drawing and editing operations, there are intersection points, end points, midpoints, center points, and vertical points as effective instruction points, and the position is displayed by writing a predetermined mark on an already existing figure. Further, when the effective instruction point is complicated, the instruction operation is enlarged.

Furthermore, a technique related to a CAD drawing creation method for shortening the time required for drawing similar drawings and reducing mistakes in creating simple drawings is also disclosed (for example, see Patent Document 1). Here, the reference point, scale, and start point coordinates, length, and direction of each line segment based on the point are stored. In addition to the variable symbols, constant values such as scale dimensions are stored as the dimensions of the figure. Then, when a portion to be changed is selected, the changed portion is flash-displayed. Then, the actual dimensions corresponding to the change are input. As a result, the graphic is changed.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments embodying the present invention will be described with reference to FIGS. In the present embodiment, a drawing processing program, a recording medium, a method, and a system used when creating a straight line segment as an object in the drawing space will be described. The drawing processing system shown in FIG. 1 is used for this drawing processing. This drawing processing system includes an input unit 10, a display unit 15, and a control unit 20.

  The input unit 10 functions as input means that accepts coordinate input, and includes input means such as a pointing device such as a mouse and a pen input tablet, and a keyboard. Various signals generated by the input unit 10 are supplied to the control unit 20.

The display unit 15 functions as display means for displaying each object recorded in the drawing data storage means and a cursor for drawing, and is configured using a liquid crystal display or the like.
The control unit 20 includes arithmetic processing means such as a CPU, data storage means such as RAM, ROM, and hard disk device, and interface means with an external device, and includes an input control unit 21, a coordinate memory 22, and a drawing control unit as control means. 23, a display control unit 24, and a drawing data storage unit 25.

  The input control unit 21 is supplied with a coordinate signal and a coordinate selection signal from the input unit 10. For example, the coordinate signal is a signal based on a position or the like instructed by the pointing device, and is used for specifying coordinates in a coordinate space (plotting space) for drawing. The selection signal is supplied when selection input (for example, click input) is performed.

  The coordinates in the coordinate space specified based on this coordinate signal are recorded as cursor coordinates in the coordinate memory 22, and the cursor is displayed at a position corresponding to the coordinates in the model space display displayed on the display unit 15. .

  The coordinate memory 22 further records data relating to the start point coordinates and end point coordinates. Specifically, when drawing an object such as a figure, the attribute, position, and size are input. For example, when a line segment is input on the drawing, the straight line input mode is set by a predetermined operation. In this case, the drawing control unit 23 assigns an object identifier indicating a straight line to this operation, and enters a start point or end point input mode.

When the selection input of the input unit 10 is performed in the start point input mode, the start point coordinates are recorded as the start point coordinates.
On the other hand, when the candidate coordinates are calculated in the processing described later in the end point input mode after the start point input mode, the intersection coordinates at that time are recorded as candidate coordinates.

  Using the start point coordinates and end point coordinates recorded in the coordinate memory 22 in this way, the drawing control unit 23 displays a start point marker and an end point marker on the display unit 15 at positions corresponding to the respective coordinates.

  When the object is completed based on the start point and the end point, the drawing control unit 23 draws the coordinates for determining the arrangement of the object (start point and end point in the case of a straight line) as the completed object as the object data storage unit. Record in the data storage unit 25. In the drawing data storage unit 25, for each created object, specific information such as an object identifier, an attribute of the object, and data regarding a coordinate range occupied by the object are recorded.

  The drawing control unit 23 executes a drawing processing program to perform processing (processing including an extension line creation stage, a candidate display stage, a dimension display stage, etc.) described later. As a result, the drawing control unit 23 functions as each means such as extension line creating means, candidate display means, and dimension display means.

  Here, the extension line creation means is a means for recording the start point coordinates of the new object set using the input means, and a means for calculating a function for generating an extension line connecting the start point coordinates and the current position coordinates of the cursor. Function.

The candidate display means functions as means for specifying the intersection coordinates between the extension line and the existing object installed in the coordinate space, and means for outputting the candidate selection means to the display means with the intersection coordinates as new processing target candidates.
The dimension display means functions as means for outputting a drawing instruction using the intersection corresponding to the candidate selection means when the candidate selection means is selected.

  A processing procedure for drawing using the drawing processing system configured as described above will be described with reference to the flowcharts shown in FIGS. Here, a process for drawing a straight line will be described. First, the drawing control unit 23 executes a process for selecting a figure type to be created (step S1-1). In the present embodiment, it is assumed that a straight line segment is generated, and the straight line input mode is set based on an instruction from the input unit 10. In this case, the screen shown in FIG. 4A is displayed on the display unit 15. The cursor C and the existing object 100 are displayed on this screen. The existing object 100 is displayed based on the coordinate data recorded in the drawing data storage unit 25. Here, it is assumed that there are three existing objects 100.

  Then, the drawing control unit 23 executes start point coordinate setting processing (step S1-2). Here, the input control unit 21 sequentially records coordinates specified based on the coordinate signal supplied from the input unit 10 as cursor coordinates in the coordinate memory 22. In this case, the display control unit 24 outputs the cursor C to the display unit 15 based on the coordinates. Then, the drawing control unit 23 waits for a selection input from the input control unit 21.

  When the input point 10 is selected and input by the input unit 10 and the input control unit 21 receives the selection signal, the drawing control unit 23 acquires the cursor coordinates recorded in the coordinate memory 22 and coordinates as the start point coordinates. Record in the memory 22. In this case, the start point marker 110 shown in FIG. 4B is set.

  When the start point is set, the drawing control unit 23 specifies the cursor coordinates using the coordinate memory 22 in which the coordinates specified by the coordinate signal sequentially supplied from the input unit 10 are recorded. Then, the drawing control unit 23 supplies straight line segment data connecting the current cursor coordinates and the start point coordinates to the display unit 15 via the display control unit 24. In this case, a straight line segment 120 shown in FIG. 4B is displayed on the display unit 15. The straight line segment 120 is displayed following the movement of the cursor C. Further, the drawing control unit 23 follows the movement of the cursor C, calculates the direction and dimensions from the start point coordinates to the current cursor coordinates, and outputs a drawing support display D including them. In the present embodiment, the dimension calculation and the output of the drawing support display D are to be changed later.

Next, the drawing control unit 23 executes candidate marker display processing (step S1-3). This candidate marker display process will be described with reference to FIG.
First, the drawing control unit 23 generates an extension line between the start point coordinates and the cursor coordinates (step S2-1). Specifically, an extension line function that generates a line (extension line) connecting the start point coordinates and the cursor coordinates is specified. In the present embodiment, a function obtained by connecting the two with a straight line is used as the extended line function.

  Next, the drawing control unit 23 specifies an intersection between the generated extension line and another object (step S2-2). Specifically, it is searched whether there is a coordinate that satisfies the previously calculated extension line function in the coordinates of the object recorded in the drawing data storage unit 25. If there is a coordinate that satisfies the extended line function, this is taken as the intersection.

  And the drawing control part 23 displays the candidate marker as a candidate selection means as a new process target candidate (step S2-3). Specifically, a candidate marker M is displayed at the specified coordinates of the intersection as shown in FIG. This candidate marker M is a selectable icon display. When there are intersections with a plurality of objects, candidate markers M are displayed for all the intersections.

  Then, the drawing control unit 23 waits for a selection input at the input unit 10 via the input control unit 21 (step S2-4). When there is no selection input in the input unit 10 (in the case of “NO” in step S2-4), the drawing control unit 23 repeats steps S2-1 to S2-3. On the other hand, when there is a selection input in the input unit 10 (in the case of “YES” in step S2-4), the process returns to the process shown in FIG.

  Here, when the supplied coordinate position where the selection input is made coincides with the display position of the candidate marker M and the candidate marker M is selected (in the case of “YES” in step S1-4), the drawing control unit 23 performs display switching based on the position of the selected candidate marker (step S1-5). Here, the distance between the selected candidate coordinates and the cursor coordinates is calculated and output as the dimension of the drawing support display D. For example, as shown in FIG. 5A, when one candidate marker M is selected, the distance from the coordinates of this candidate marker M to the cursor coordinates is calculated and output as a drawing support display D.

  Then, the drawing control unit 23 waits for an end point input (step S1-6). In this case, the drawing control unit 23 follows the movement of the cursor C, calculates the distance from the selected candidate coordinate to the current cursor coordinate, and outputs this drawing support display D. When the selection input is performed again, the drawing control unit 23 determines the coordinates of the object (here, the line segment) using the selected cursor coordinates as the end point coordinates.

  Then, the drawing control unit 23 performs object recording processing (step S1-7). Here, the drawing control unit 23 records data relating to the determined object in the drawing data storage unit 25 based on the start point coordinates and the end point coordinates.

  In step S1-4, if there is an intersection between the extension line from the start point coordinate to the cursor coordinate and another object within the fixed range provided around the current cursor coordinate, the intersection is recognized as selected. You may make it do. Thereby, it can connect also to the coordinate which is displaying the candidate marker M.

  On the other hand, when the supplied coordinate position where the selection input is performed is different from the display position of the candidate marker M (in the case of “NO” in step S1-4), the drawing control unit 23 sets the selected input coordinate as the end point. An object recording process is performed as coordinates (step S1-7).

  In continuous line segment input, as shown in FIG. 5B, candidate marker display processing is executed starting from the previous end point, and a candidate marker M is output at the intersection of the extension line and the object. When the candidate marker M is selected, the distance from the intersection corresponding to the candidate marker M is output as a drawing support display D as shown in FIG.

As described above, according to the present embodiment, the following effects can be obtained.
In the above embodiment, the drawing control unit 23 executes candidate marker display processing (step S1-3). In this case, the drawing control unit 23 generates an extension line between the start point coordinates and the cursor coordinates (step S2-1). Next, the drawing control unit 23 specifies an intersection between the generated extension line and another object (step S2-2), and displays candidate markers (step S2-3). When the candidate marker M is selected, the drawing control unit 23 performs display switching based on the position of the selected candidate marker (step S1-5). Here, the distance between the selected candidate coordinates and the cursor coordinates is calculated and output as the dimension of the drawing support display D. When creating a design drawing, it may be desirable to know the distance from other objects rather than the dimensions of the object being created (here, a line segment). For example, when piping is performed in construction drawings, the distance from a wall or other piping is more important than the length of the piping. Even in the case of drawing in this way, the distance can be efficiently grasped by switching the display.

  In the above embodiment, the drawing control unit 23 specifies the intersection between the generated extension line and another object (step S2-2). Then, the drawing control unit 23 displays candidate markers (step S2-3). This makes it possible to easily select a target object candidate whose distance is to be measured. In particular, even when a plurality of objects are involved, candidates are displayed using extension lines, so that selection can be performed without performing enlarged display or the like, so that drawing work can be performed efficiently.

In addition, you may change the said embodiment into the following aspects.
In the above embodiment, the drawing control unit 23 specifies the intersection between the generated extension line and another object (step S2-2). And the drawing control part 23 displays the candidate marker corresponding to this intersection (step S2-3). Instead, the intersection may be selected based on the specific information (attribute or name) of another object. In this case, the drawing data storage unit 25 stores the specific information of each object in association with the coordinate data. And the drawing control part 23 acquires the specific information of the target object which calculates the intersection of an extension line. The identification information of the target object is input from the input unit 10 for drawing.

  Moreover, the specific information of the target object can be acquired based on the graphic type selected in step S1-1. In this case, a correspondence table between graphic types and target object specific information is recorded in advance in a predetermined data storage unit.

  Then, as illustrated in FIG. 6A, the drawing control unit 23 specifies an intersection point between the coordinates of the target object and the extension line. Then, as shown in FIG. 6B, a candidate marker M is output at this intersection. Since the intersection used for display is narrowed down by the specific information, selection of the candidate marker M is facilitated.

  In the above embodiment, the drawing control unit 23 specifies the intersection between the generated extension line and another object (step S2-2). And the drawing control part 23 displays the candidate marker M corresponding to this intersection (step S2-3). Instead, as shown in FIG. 7, only the candidate marker M in the moving direction of the cursor C may be displayed. In this case, an extension line in the direction of the cursor coordinates from the start point coordinates is generated. Thereby, since the intersection is narrowed down, selection of the candidate marker M becomes easy.

In the above embodiment, the drawing control unit 23 specifies the intersection between the generated extension line and another object (step S2-2). And the drawing control part 23 displays the candidate marker M corresponding to this intersection (step S2-3). Instead, it may be limited to a predetermined range of intersections. In this case, data relating to the number of target intersections of intersections is recorded in a predetermined data storage unit. And the drawing control part 23 selects the intersection of the number of object intersections from the nearer side from the starting point, and displays the candidate marker M corresponding to this intersection.

  Further, the candidate marker M corresponding to this intersection point can be displayed only on the intersection point existing within a predetermined distance from the starting point. Thereby, since the intersection is narrowed down, selection of the candidate marker M becomes easy.

  In the above embodiment, the drawing control unit 23 displays the candidate marker M corresponding to this intersection (step S2-3). In this case, the specific information (attribute or name) of another object may be output in association with the displayed candidate marker M. In this case, the drawing data storage unit 25 stores the specific information of each object in association with the coordinate data. Then, the drawing control unit 23 acquires the specific information of the object that generated the intersection from the drawing data storage unit 25 and outputs it to the display unit 15 together with the candidate marker M. Thereby, the candidate marker M can be selected using specific information (attribute or name).

  In the above embodiment, the drawing control unit 23 displays the candidate marker M corresponding to this intersection (step S2-3). Instead of this, the extension line may have a thickness or a width. In this case, the drawing control unit 23 identifies another object within a predetermined range from the extension line, and sets the closest coordinate to the extension line as the intersection among the coordinates constituting the other object. As a result, even if the object is displaced from the extension line, if it is in the vicinity thereof, it can be a candidate for processing.

  In the above embodiment, input of a straight line segment is used, but it can also be used for input of a curved line segment. In this case, the extension line is generated using a curve function calculated based on the start point coordinates and the cursor coordinates. Also by this, the candidate marker M can be displayed.
