This embodiment is different from the first embodiment in that the dimension lines of the bearing graphic are arranged. Hereinafter, only different parts from the first embodiment will be described, and overlapping parts will be denoted by the same reference numerals and description thereof will be omitted.

First, the functional outline of the drawing support apparatus 100 according to the present embodiment will be described.
FIG. 19 is a functional block diagram showing an outline of functions of the drawing support apparatus 100.
As illustrated in FIG. 19, the drawing support apparatus 100 includes a graphic data storage unit 10, a basic data input unit 12, a part graphic selection unit 14, and a graphic display unit 16.

FIG. 20 is a diagram schematically showing the data structure of figure specification data.
The figure specification data includes data defining the priority order for arranging the dimension lines of the part figure.
As for the name of the dimension line, the same name is set as long as the variables of the values to be poured based on the basic specifications are the same even if the part figures are different. In addition, as shown in FIG. 20, the position of the dimension line is set in the vertical, left and right positions as viewed from the part graphic, and is arranged in the order of the smaller dimension value from the part graphic. . Also, the interval between the dimension lines is set.

Next, processing executed by the CPU 50 will be described.
The CPU 50 further activates a predetermined program stored in a predetermined area of the ROM 52, and executes the drawing support process shown in the flowchart of FIG. 21 according to the program.

FIG. 21 is a flowchart showing the drawing support process.
The drawing support process is a process realized as the basic specification input unit 12, the component graphic selection unit 14, the graphic display unit 16, the component graphic arrangement unit 18, the component graphic enlargement / reduction unit 20, and the dimension line arrangement unit 24. When the process is executed, the process proceeds to step S300 as shown in FIG.
In steps S300 to S308, the same processing as in steps S100 to S108 is executed, and the process proceeds to step S310, and the dimension line having the highest priority among the unprocessed dimension lines based on the priority order of the figure specification data. Is acquired, and the process proceeds to step S312.
In step S312, it is determined whether or not the acquired dimension line name exists in the figure specification data of the selected part graphic. If it is determined that the dimension line name exists (Yes), the process proceeds to step S314. Based on the figure specification data of the selected part figure, a dimension line related to the name of the acquired dimension line (hereinafter referred to as a target dimension line) is arranged, and the process proceeds to step S316.

  In step S316, the target dimension line is moved according to a predetermined movement rule. The first movement rule is a rule that defines that the target dimension line is moved so that a dimension line having a smaller dimension value is arranged closer to the figure of the bearing. The second movement rule is a rule that stipulates that the target dimension line is moved so that the interval between the dimension lines becomes the set interval. The third movement rule is a rule that defines that the target dimension line is moved so that the number of dimension lines arranged on the left and right of the bearing graphic is equal. These movement rules may be applied as the process of step S316, or may be stored in the storage device 62 as movement rule data, and the movement rule data may be read and applied in the process of step S316.

Next, the process proceeds to step S318, where it is determined whether or not the processing of steps S310 to S316 has been completed for all dimension line names, and when it is determined that the processing has been completed for all dimension line names (Yes). Finishes a series of processing and returns to the original processing.
On the other hand, when it is determined in step S318 that the processing has not been completed for all dimension line names (No), the process proceeds to step S310.
On the other hand, when it is determined in step S312 that the acquired dimension line name does not exist in the graphic data of the selected part graphic (No), the process proceeds to step S318.

Next, the operation of the present embodiment will be described.
In the drawing support device 100, when the creation of a figure is requested, through steps S300 to S308, the selected part figure is combined and the bearing figure is displayed in the same manner as in the first embodiment.

  When the bearing graphic is displayed, the dimension line names are acquired in descending order of priority through steps S310 and S312, and whether or not the acquired dimension line name exists in the graphic data of the selected part graphic. Is determined. As a result, if it is determined that the dimension line name exists, the target dimension line is arranged through steps S314 and S316, and the target dimension line moves according to a predetermined movement rule. Such a process is performed for all dimension line names.

FIG. 22 is a diagram showing a figure of the bearing before dimension line arrangement.
When the dimension line is not moved according to the movement rule, each dimension line of the selected part graphic is arranged at a position set in the selected part graphic as shown in FIG. Therefore, the dimension lines may intersect depending on the combination of the selected part figures. Further, if attention is paid to one selected component graphic, the dimension lines of the selected component graphic are arranged in the order closer to the selected component graphic in descending order of the dimension value. They are not arranged in order from the smallest dimension value. Further, the distance between the dimension lines and the number of dimension lines arranged on the left and right sides of the bearing graphic are not uniform. Therefore, there is a problem that the dimension lines are cluttered and it is difficult to grasp the dimensions from the figure of the bearing.

FIG. 23 is a diagram showing a bearing figure after arrangement of dimension lines.
On the other hand, when the dimension line is moved according to the movement rule, each dimension line of the selected part figure is arranged closer to the bearing figure as the dimension line having a smaller dimension value, as shown in FIG. The interval between the dimension lines becomes the set interval, and the number of dimension lines arranged on the left and right sides of the bearing graphic is even.

  In FIG. 22, with respect to the dimension line on the left side of the bearing graphic, the dimension of the bearing is in the order of 60 [mm], 20 [mm], 30 [mm], 40 [mm] (actual bearing dimensions). The dimension lines on the right side are arranged in the order of 70 [mm] and 50 [mm] in the order of the bearing figure. On the other hand, in FIG. 23, the dimension line on the left side of the bearing graphic is arranged near the bearing graphic in ascending order of the dimension values 30 [mm], 40 [mm], and 60 [mm]. The right dimension line is arranged near the bearing figure in the order of smaller dimension values of 20 [mm], 50 [mm], and 70 [mm].

In FIG. 22, each dimension line of the figure of the bearing is arranged so that the interval between the dimension lines is sparse. On the other hand, in FIG. 23, the left and right dimension lines of the bearing figure are 15 [cm], 10 [cm], and 10 [cm] (distance on the drawing) from the vicinity of the bearing figure, respectively. Has been placed.
In FIG. 22, four dimension lines are arranged on the left side and two dimension lines on the right side of the bearing graphic. In contrast, in FIG. 23, three dimension lines are arranged on the left and right of the bearing graphic.
Thus, in the present embodiment, each dimension line of the selected part graphic is arranged according to the priority order of arranging the dimension lines of the part graphic.

  Thereby, even when dimension lines exist in the part figure, the dimension lines are arranged according to the priority order when the part figures are combined, so that the work of arranging the dimension lines becomes unnecessary, and the work efficiency is further improved. be able to.

If executed at step S400, first, the process proceeds to step S400 as shown in FIG.
In steps S400 to S408, the same processing as in steps S100 to S108 is executed, and the process proceeds to step S410, and two corresponding end points are found in the two selected part figures based on the figure specification data of the selected part figure. If it is determined whether or not two corresponding end points exist (Yes), the process proceeds to step S412.

In step S412, the two corresponding end points of the selected part graphic are selected, the process proceeds to step S414, the position of the selected end point is acquired from the graphic data, and the process proceeds to step S416.
In step S416, the outline data connecting the two end points is created by updating the figure specification data of the selected part figure, the created outline is displayed on the display device 64, and the process proceeds to step S618. The thickness of the outline is set, the series of processes is terminated, and the original process is restored.

On the other hand, when it is determined in step S410 that the end point exists only in one of the two selected part figures (No), the process proceeds to step S422, and one end point of the selected part figure is selected, and the process proceeds to step S424. Then, the position of the selected end point is acquired from the figure specification data, and the process proceeds to step S426.
In step S426, the position of the end point corresponding to the selected end point is calculated from the other of the two selected part figures based on the figure specification data of the selected part figure, and the process proceeds to step S416.

Next, the operation of the present embodiment will be described.
In the drawing support device 100, when the creation of a figure is requested, through steps S400 to S408, the selected part figure is combined and the bearing figure is displayed in the same manner as in the first embodiment.

FIG. 27 is a diagram showing component figures of the inner ring, the outer ring, and the cage before the outline is displayed.

Also, the lower left end point 650 of the retainer part graphic 612 and the outer diameter line 652 of the part graphic 606 are outline lines, and the lower right end point 650 of the retainer part graphic 612 and the outer diameter line of the part graphic 606 are displayed. It is necessary to connect 652 with an outline.
When the bearing graphic is displayed, it is determined through step S410 whether or not two corresponding end points exist in the two selected component graphics.

FIG. 28 is a diagram showing component diagrams of the inner ring, the outer ring, and the cage after the outline is displayed.
As shown in FIG. 28, since the lower left end point 650 of the part graphic 602 corresponds to the upper left end point 650 of the part graphic 606, there are two corresponding end points 650 in the relationship between the selected part graphics 602 and 606. Determined. Therefore, the corresponding two end points 650 are selected through steps S412 to S416, the position of the selected end point 650 is acquired, and the outline 654 connecting the two end points 650 is displayed.

Similarly, since the lower right end point 650 of the part graphic 602 and the upper right end point 650 of the part graphic 606 also correspond, an outline 654 connecting these two end points 650 is displayed through steps S410 to S416.
Further, in the relationship between the selected part graphics 606 and 612, the end point 650 exists at the lower left of the part graphic 612. However, since the corresponding end point does not exist in the part graphic 606, the end point 650 exists only in one of the two selected part graphics. It is determined that it does not exist. Therefore, one end point 650 is selected through steps S422 and S424, and the position of the selected end point 650 is acquired. Further, through step S426, the position of the end point corresponding to the selected end point 650 is calculated on the outer diameter line 652 of the part graphic 606. Then, through step S416, an outline 654 connecting these two end points is displayed.

Similarly, for the lower right end point 650 of the part graphic 612 and the outer diameter line 652 of the part graphic 606, an outline 654 connecting these two end points is displayed through steps S410, S422 to S426, and S416.
In this way, in the present embodiment, the outline that connects the end point set to one of the selected component graphics and the other of the selected component graphics is displayed.

As a result, even when component graphics are combined, even when the component graphics need to be coupled with the outline, the operation of coupling with the outline is not necessary, and the work efficiency can be further improved.
In addition, since the end points can be recognized by combining part figures, there are fewer calculation errors than when the end points are calculated by a program, etc., and the degree of completeness of the drawing can be increased. Development time can be reduced because less time is required for line position calculation.

Furthermore, in the present embodiment, when the end points are set for both of the selected part figures, the outline connecting the end points is displayed, and when the end points are set for only one of the selected part figures, the selection is made. The other end point of the part graphic is obtained, and the end point set to one of the selected part figures and the outline connecting the obtained end point are displayed.
Thereby, if an end point is set in at least one of the selected component figures, an outline can be displayed.
