Abstract

PROBLEM TO BE SOLVED: To reduce operation for enlarging and reducing a screen and to improve the efficiency of a drawing time by fully automatically displaying the X-axial and Y-axial dimension values of a ruled line and the centers of a circle and an arc from a reference surface and the dimension values of the diameter of the circle and the radius of the arc at specific positions. SOLUTION: To display the X-axial and Y-axial dimension values of the ruled line, circle, and arc constituting a figure from the reference surface at the periphery of the figure differently between only the ruled line and only the circle and arc, the extraction of the ruled line, circle, and arc in the figure is indicated on a keyboard 2. Then a central processor 3 discriminates the ruled line, circle, and arc, and the centers of the circle and arc and also calculates the dimension values from the reference surface or a reference point, and automatically displays them at specified dimension value display positions and also automatically displays the dimension values of the diameter of the circle and the radius of the arc. Consequently, the dimension value display position of the ruled line and the dimension value display positions of the circle and arc can be dispersed vertically and horizontally about the figure by specifying only the size reference surface and size value display positions.

When displaying the dimension values of the drawing, the cursor is moved to the first ruled line 7 which is the reference plane of the X axis on the display device 1 screen of FIG. Next, the cursor is aligned with the second ruled line 8 using the keyboard 2. However, since the distance between the first ruled line 7 and the second ruled line 8 in the X-axis direction is so small that it is difficult to identify them, FIG.
25, after partially enlarging the screen of the display device 1 of FIG. 25, the cursor is moved to the second ruled line 8, and the third ruled line 9 is displayed.
The cursor is also adjusted using the keyboard 2. Next, the cursor is aligned with the fourth ruled line 10 using the keyboard 2. However, since the ruled line 10 is not displayed in the enlarged view of FIG. 26, the screen is returned to the display device 1 screen of FIG. Is matched. Here, when the distance between the fourth ruled line 10 and the fifth ruled line 11 in the X-axis direction is small and it is difficult to identify, the ruled line 10 and the fifth ruled line 11 are further enlarged as shown in the enlarged view of FIG.
Is performed and the cursor is positioned on the ruled line 10. When the number of ruled lines is large and the shape is complicated, the spacing between ruled lines is often small in this way.However, in order to place the cursor on all ruled lines and display the dimension value, it is necessary to repeat partial enlargement many times. In addition, there is a disadvantage that the time required to move the cursor to the ruled line is enormous, and the dimension value is leaked due to forgetting to move the cursor to the ruled line.

An object of the present invention is to provide a method for displaying a dimension value of a drawing in which such a disadvantage is eliminated.
