Abstract

PURPOSE:To discriminate easily the dimension of a display graphic form by varying the scale of measure displayed to measure the length of the display graphic form. CONSTITUTION:According to control signals 101, 102 from a graphic display control section 1, measure display position information from a measure display position control section 2 and measure display size information from a measure display scale control section 3 are stored in a measure display processing section 5 as measure information. Graphic information is stored in the graphic processing section 4 corresponding to a control signal 103 from the graphic display control section 1. The measure information of the measure display processing section 5 and the graphic information of the graphic display processing section 4 are superimposed mutually and the result is stored in a memory of a picture display processing section 6 as integrated display information and read and displayed on a graphic information output display section.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a graphic display method, and particularly to a CAD (Computer
The present invention relates to a graphic display method that improves the measure display method used when performing graphic design using the ter Aided Design method.

[Conventional technology]

Conventionally, in this type of graphic display method using a measure display, a mesh displayed on a predetermined information output device with regular intervals both vertically and horizontally is used to display measures when designing figures using CAD. However, the size of the message 7^ remains unchanged in response to enlargement or reduction of the display figure displayed on the information output device. Therefore, when a figure is input to the information output device When doing so, the dimensions of the displayed figure are set by counting the magnification of the enlargement or reduction of the displayed figure and the number of squares of the mesh item, and a predetermined figure is drawn (for example, ASCII 8mal
I CANDY system).

[Problem that the invention seeks to solve]

In the case of the conventional mesh display method described above, it is clear that the scale of the displayed figure displayed on the screen of the information output device with respect to the actual object is 2, but the dimensions of all the partial figures are different from each other. The disadvantage is that if it is not filled out, it cannot be determined by anyone other than the designer. Also, when entering a figure with a certain dimension, you must count its scale and the number of mesh squares, and the diagonal dimensions are based on the mesh square and scale. , there is an operational drawback in that it cannot be determined without calculating it each time.

[Means for solving problems]

The graphic display method of the present invention displays predetermined graphic information, etc. on a CRT.
In a graphic display system that displays on a graphic information output display section including (Cathode Ray Tube), etc., in response to the graphic information displayed on the graphic information output display section, a display is performed to measure the length of the displayed figure. The measure display scale control means is provided to vary the scale of the measure to be displayed.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the main parts of an embodiment of the present invention. As shown in FIG. 1, this embodiment includes a graphic display control section 1, a measure display position control section 2, a measure display scale control section 3, a graphic display processing section 4, and a measure display processing section 5. , a screen display processing section 6, and a graphic information output/display section 7.

In FIG. 1, control signals 101 and 102 output from the graphic display control section 1 are input to the corresponding measure display position control section 2 and measure display scale control section 3, respectively. The measure display position control section 2 and the measure display scale control section 3 are each provided with a memory that stores control information related to the measure display position and the measure display scale. , control information corresponding to each control signal is output and sent to the measure display processing section 5.

The measure display processing section 5 is equipped with a memory that stores measure information to be displayed on the graphic information output display section 7, and stores the measure information displayed on the graphic information output display section 7. Corresponding to the information, measure information of the display position and display scale specified by the graphic display control unit 1 is stored.

On the other hand, the control signal 103 output from the graphic display control section 1
is input to the graphic display processing section 4. Graphic display processing section 4
is equipped with a memory for storing predetermined graphic information to be displayed on the graphic information output display section 7, and a control signal 103 is provided.
The graphic information designated by the graphic display control unit l in response to the input is stored in the memory.

Measure information that specifies the display position and display scale stored in the measure display door section 5 and the graphic display processing section 4
The predetermined graphic information stored in is read out via control signals 104 and 105 sent from the graphic display control section 1, respectively, and input to the screen display processing section 6. The screen display processing section 6 is equipped with a memory that stores the graphic information and measure information to be displayed on the graphic information output display section 7, and is sent from the graphic display processing section 4 and the measure display processing section 5, respectively. The graphic information and the measure information are superimposed on each other and stored in the memory as integrated display information. Next, the integrated display information is read out from the screen display processing section 6 via the control signal 106 sent from the graphic display control section 1 to the screen display processing section 6, and is output to the graphic information output display section 7. entered and displayed.

Note that the graphic information output display section 7 is generally a CR
T etc. are often used.

Below, figure display control section 1, measure display position control section 2,
Through the actions of the measure display scale control section 3, graphic display processing section 4, measure display processing section 5, screen display processing section 6, etc., predetermined displays are sequentially displayed on the table/display screen of the graphic information output display section 7. Corresponding to the figure, a measure whose display position is enlarged or reduced, or whose display position is moved or rotated is displayed in a superimposed manner in accordance with a predetermined instruction request.

〔Effect of the invention〕

As explained above, the present invention makes the display scale of the measure displayed superimposed on the display figure variable.
This has the effect that the dimensions of the displayed graphic can be easily determined.
