2. Description of the Related Art FIG. 9 is a view for explaining a method of displaying dimension values of a drawing conventionally drawn by using a CAD device, where 1 is a display device using a CRT or the like, 2 is graphic data, etc. A central processing unit (hereinafter referred to as a CPU) 3 for processing data input by the keyboard 2 to display a graphic or the like on the display device 1 and 4 for displaying data on the display device 1. It is a plotter unit for printing the drawing 5 on paper. In creating a drawing, the CPU 3 performs arithmetic processing on graphic data input by the keyboard 2, and the drawing 5 and the graphic 6 are displayed on the screen of the display device 1. Note that, here, for convenience, three holes 7, 8, and 9 are shown, and the surface serving as the display reference of the dimension values of the three holes 7, 8, and 9 is the reference surface 10, and from the reference surface 10 of the first hole 7. The first dimension value 11 which is the distance of 60 is 60, and the dimension auxiliary line 12 displayed parallel to the reference plane 10 and the dimension line 13 displayed at a right angle to the reference plane 10 from the center of the first hole 7 It is displayed near the intersection. Similarly, the second dimension value 14 which is the distance of the second hole 8 from the reference surface 10 is 120, and the third hole 9
The third dimension value 15 which is the distance from the reference plane 10 of is 18
It is 0.

[0003]

When creating a drawing, for example, the circular figure of the first hole 7 and the first dimension value 11 of FIG. 9 are used.
In order to display, the keyboard 2 is used to move a cursor on the screen to designate a predetermined position as shown in FIG. 10 which is an enlarged view of the screen of the display device 1 of FIG. After drawing the circle figure in the drawing using the drawing function, select the automatic dimension display function in the operation menu, and draw the reference plane 1
By designating the circle of 0 and the first hole 7 by moving the cursor on the screen using the keyboard 2 described above, the first hole 7
The first dimension value 11, which is the distance in the Y direction on the screen from the reference plane 10 of, is automatically displayed on the screen together with the dimension auxiliary line 12 and the dimension line 13. The dimension value automatically displayed in this way may be changed by design change. For example, when the position in the Y direction on the screen of the second hole 8 shown in FIG. 10 which is an enlarged view of the screen of the display device 1 of FIG. 9 is changed by design change, the operation menu is changed to the parametric function (displayed size). By changing the value, the position of the figure indicated by the dimension value can be automatically transformed) and the second dimension value 14 for changing the dimension value is specified by moving the cursor on the screen with the keyboard 2. After that, when the fourth dimension value 16 is input and replaced in that portion with the keyboard 2, the position of the circular figure of the second hole 8 in the Y direction from the reference plane 10 on the screen is determined by the CPU 3.
Then, the position in the Y direction of the circular figure of the second hole 8 can be automatically changed according to the input fourth dimension value 16 by performing the arithmetic processing in step (4). This will be described in detail, for example, with reference to FIG.
Initially, as shown in, the position in the Y direction on the screen from the reference surface 10 of the second hole 8 is 120, and the second dimension value 14 is automatically displayed as 120 by the automatic dimension display function. If it is necessary to change to 145, the operation menu is selected for the parametric function, and the second dimension value 14
120 is designated by moving the cursor on the screen with the keyboard 2, and that portion is manually input from the keyboard 2.
If you enter 45 and replace it with the fourth dimension value 16,
As shown in FIG. 1, the second dimension value 14 is replaced with 145, and the position in the Y direction on the screen from the reference plane 10 of the circular figure of the second hole 8 is automatically changed from 120 to 145 by the parametric function. Is changed to. The positions of the dimension auxiliary line 12 and the dimension line 13 on the screen in the Y direction are also automatically moved. When the second dimension value 14 is replaced with the fourth dimension value 16, the keyboard 2 is used to manually input, so that there is a possibility that an erroneous input may occur, for example, inputting 145 where 145 should be input. . Therefore, it is necessary to find and correct these erroneously entered and displayed dimension values, but even if the dimension values are displayed differently, the shape of the dimension values displayed on the screen is the same. There is a drawback in that it is difficult to find a dimension value that has been input by mistake and displayed.

The present invention proposes a display method which eliminates the above drawbacks and makes it easy to identify only the dimension values displayed by manual input which may have been erroneously input in the dimension values of the drawing. is there.

[0005]

[Means for Solving the Problem] It is necessary to clarify the location where there is a possibility of a dimensional value input error. However, the dimensional value displayed on the screen can be manually input and the dimensional value can be automatically displayed. The first step of distinguishing between the measured dimension values and the first step
Among the dimension values distinguished in the step of, the second step of storing the dimension values displayed by manually inputting the dimension values and the identification mark near the dimension values displayed by the manual input saved in the second step above It is possible to display the identification mark for identifying the automatically displayed dimension value, by sequentially performing the third step of displaying, and adding the identification mark in the vicinity of the dimension value displayed by manually inputting the dimension value. .

[0006]

According to the present invention, the dimension values displayed on the screen are distinguished by the display method, and the identification value is added in the vicinity of the dimension value displayed by manual input of the dimension value to automatically display the dimension value. It can be identified as.
