Abstract

PURPOSE:To improve the operability of a digitizer system by performing a zooming operation of a sampling form displayed on a screen of a CAD system via a digitizer device during a sampling operation. CONSTITUTION:A zooming menu key 5 is provided to a function menu 2 for the sampling auxiliary function which is prepared at a digitizer 102 to perform the switch of an interpolation mode, etc. Then the digitizer 102 can perform a sampling operation when a menu for digitizing operation is selected via a CAD 101. The key 5 of the menu 2 is selected when a zooming operation is required during a sampling operation. Thus the sampling coordinates of the following two times are informed to the CAD 101. Then two points under sampling on a drawing is pointed by a digitizing cursor. As a result, the zooming effect is drawn on a graphic display 11 via the software of the CAD 101.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is based on C! The present invention relates to a graphic input method in an AD system and a CAM system.

[Conventional technology]

Figure 4 is a diagram showing the configuration of a conventional digitizer system.
Figure (101) shows the configuration of the CAD device.

Next, the operation will be explained.

In the conventional digitizer device, as shown in FIG. 5, during the sampling operation (2) on the digitizer side.

[Problem to be solved by the invention]

Conventional digitizing systems are configured as 9 or higher, so in the operation procedure, when zooming operation is required during f fgling, the operator has to go to the trouble of c
You have to go back to the AD device and perform the zooming operation.
sampling operation.

There were problems such as interruptions each time. especially.

In systems with large digitizers.

Since the CAD device and the digitizer are often far apart, there are problems such as the operator having to move around.

This invention was made to solve the above-mentioned problems, and it facilitates the operator's zooming operation when sampling with a digitizer, and also makes it easier for CAD devices,
It is an object of the present invention to provide a digitizer system with good operability and less wasteful movement by an operator between digitizers.

[Means to solve the problem]

The digitizer system according to the present invention enables a graphic display to be zoomed only by operations on the digitizer side when zooming becomes necessary during sampling on the digitizer side.

[Effect]

The digitizer system according to the present invention is provided with a key switch for instructing zooming on the digitizer side, and after pressing this switch, the digitizing cursor on the digitizer side can be used to specify two points on the digitizer board. The display center is calculated at a display magnification of 9 so that the area within the rectangle indicated by the dot is drawn in the display area of the graphic display on the CAD device side, and a graphic display is performed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the digitizer system of the present invention. In FIG. A zoom menu ke7 (5) t is provided here.

Next, the operating procedure will be explained according to FIG.

Select the digitizing operation menu on the CAD side f1+
Then, the sampling operation (2) on the digitizer side becomes possible. During the sampling operation, at the point when zooming operation becomes necessary (3), select the zooming menu in the sampling auxiliary menu (2) shown in Figure 1 (4).

Notify the CAD device side to consider it as a zooming area. Therefore, use the digitizing cursor to indicate the two points on the drawing that are being sampled (5) K?
), the zooming results are drawn on the graphic display using the software of the CAD device.

The situation at this time will be explained in detail with reference to FIG.

The shape currently being f-ampled looks like ■.

Assume that it is displayed on a graphic display of a CAD device. At this time, if you want to enlarge the display, like ■-a, the two points inside the area displayed on 9 screens, and conversely, if you want to reduce the display, like ■-b, Zooming is performed by specifying two points outside the area displayed on the 9-screen. This allows CAD
The software on the device side calculates the 9 display magnification and 1 display center so that the area within the designated rectangle becomes the display area of the graphic display, and displays it on the graphic display. The display results are ■-a, ■
-Become like a.

In the above embodiment, zooming was added as one menu of the sampling auxiliary function provided in the digitizing cursor section in order to give zoom operation instructions on the digitizer side. Similar effects can be achieved with general digitizer systems that use auxiliary menus. Also, other than zoom operations.

For example, if a panning operation (movement of only the display center) can be instructed from the digitizer side, the same effect can be achieved.

〔Effect of the invention〕

As described above, according to this invention, ? The zooming operation during sampling can now be performed on the digitizer side, so the sampling operation is not interrupted.
This has the effect of significantly improving operability when sampling while viewing on a graphic screen.
