6 is a flowchart specifically showing a series of operations from the movement of the cursor to the confirmation of elements and the automatic display of dimension values.

First, a description will be given with reference to FIG. The worker arranges the drawing target model in the three-dimensional space (S1). That is, the drawing target model is displayed on the screen of the display device 2 via the input device 3. The drawing model information management unit 7 stores the coordinate information and the dimension value information of each element of the drawn model in the database (S2). The dimension value automatic display control unit 11 confirms whether the graphic processing device is in the dimension value automatic display mode (S3). When the dimension value automatic display control unit 11 determines in step 3 that the dimension value automatic display mode is in the dimension value automatic display mode, the cursor coordinate information management unit 8 detects the coordinate information of the moving cursor and constantly manages the coordinate information (S4). ).
When it is determined in step 3 that the automatic dimension value display control unit 11 is not in the automatic dimension value display mode, the processing ends (S).
3). Next, the cursor coordinate matching search unit 9 performs step 4
The coordinate information of the cursor detected in step S1 and the coordinate information of each element stored in the database in step S2 are collated to determine whether they match (S5, coincidence determination step). The element highlight control unit 10 highlights the matched element when the cursor coordinate matching search unit 9 determines that they match (S6). Next, the dimension value automatic display control unit 11 reads out the dimension value information of the matched element from the database of the drawing model information management unit 7 and displays it on the screen (S7, dimension display step). The dimension value drawing unit 12 draws the dimension value displayed on the screen as it is on the drawing, or confirms the dimension value display position designation from the operator and draws the dimension value at the designated position ( S8).

Next, a series of operations from the movement of the cursor to the confirmation of the element and the automatic display of the dimension value will be specifically described with reference to FIG. The operator moves the cursor by operation as necessary (S11). The operation data by the operator is input to the cursor coordinate information management unit 8 via the input device 3. Each time the cursor moves, the cursor coordinate information management unit 8 detects the coordinates where the cursor is located and always holds the latest cursor coordinate information (S12). Next, the cursor coordinate collation search unit 9 collates the coordinate information of the cursor obtained in step 12 with the coordinate information of each element of the drawing model created in advance and stored in the database, and the coincidence is obtained. It is determined whether or not (S13, S14,
Matching determination step). When the element highlight control unit 10 determines in step 13 that the elements match, the element highlighting controller 10 highlights the matched elements (S14, S15). If it is determined that they do not match, the process returns to step 11 to continue moving the cursor. After the matching element is highlighted, the automatic dimension value display control unit 11 reads the dimension value information for the matching element from the database in which the drawing model information created in advance is stored, and the dimension value is displayed on the display device. No. 2 is displayed on the screen (S16, dimension display step). When drawing the dimension value displayed on the screen in the drawing, the operator performs the work of element determination. Dimension drawing part 1
2 determines whether or not the operator has decided the element (S17). When it is determined that the element has been decided, the displayed dimension value is drawn on the drawing (S1).
8). When it is determined that the element has not been confirmed, the process returns to step 11 to continue the cursor movement. When the cursor moves away from the element due to the continuation of the cursor movement, the element highlight display and the automatic display of the dimension value are not performed. Disappear.

The case of automatically displaying the dimension value by the method shown in FIGS. 2 and 3 will be described with reference to FIGS. 4 and 5. FIG. 4 is a drawing showing the circles, points, and line segments drawn on the screen of the display device 2.

The coordinates of are also included. In this database, data is stored in the order in which it is drawn by the worker. This database is drawn so as to always hold the updated data as the coordinate information and dimension value information of the line segment after the division when a command such as division is executed for the line element C during the design work. It is managed by the model information management unit 6.

Next, the mouse for confirming the element and the mode for automatically displaying the dimension value will be described with reference to FIGS. 5 (a) and 5 (b).
