Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a graphic processing device called CAD.

[0002]

2. Description of the Related Art In recent years, when designing complicated shapes, C
Design work using AD has become widespread, and the operation mode of screen display when approaching a screen composed of a large amount of data shows the operability of the CAD system itself.

In the design work on a complicated drawing, the operator needs to enlarge the screen and move the screen so that the focused portion is on the screen for a portion that requires detailed editing.

In this case, the operator has to perform a screen enlargement / reduction operation,
And you have to move the screen, but when performing this series of work, the operator registers the screen scaling ratio,
It was necessary to give that value to the system to display the screen, or to specify the range of the enlarged portion each time by dragging the mouse. Regarding the movement of the screen, it is necessary for the operator to specify the displacement and direction associated with the movement each time.

A conventional image processing apparatus will be described below. FIG. 4 is a block diagram of a conventional graphic processing device. In FIG. 4, 1 is a central processing unit for processing requested information, 2 is a display device for displaying windows, graphic elements, characters, etc., 3 is a keyboard, tablet, mouse, etc. for inputting data such as characters, numerical values and positions. An input device, 4 is a main storage device that stores a running program such as an operating system and a window system, 12 is an enlargement / reduction ratio input unit that receives an input of a scale value when a worker changes the scale, and 13 is a screen movement. Screen movement phase input unit that receives an input of the movement distance or the movement direction, 9 is a scale change processing unit that calculates a magnification based on the scale value of the current screen and the scale value given to the operator, and 10 is an input A screen movement processing unit for calculating a phase for the calculated distance and direction, 14 is a scale change processing unit 9, and a screen movement processing unit 1.
The secondary storage device 5 is a screen display unit that displays a screen with the setting obtained by 0.

FIG. 5 is a processing flowchart of the conventional graphic processing apparatus. The conventional processing will be described below.

The operator gives a scale value as a numerical value, or inputs a function key or the like when using the automatic calculation of the enlargement / reduction ratio performed by the system (S
11).

The magnification is calculated using the current scale value and the value given in step 11 (S12).

The screen is displayed (S13). To change the scale further, repeat the above operation.

In order to change the position of the screen display, the operator specifies the distance and direction with numerical values or with the mouse (S1).
4).

The coordinates obtained by calculating the moving distance and the moving direction are obtained from the values given in step 14 (S15).

The screen is displayed, and if insufficient, the above moving operation is repeated (S16). As described above, when the entire edited portion on the drawing is displayed on the screen, it is necessary to give the system information for calculating the enlargement / reduction ratio every time. Also, when the scaling ratio is given as a value, the screen is scaled up or down based on the reference points set by the system, so it is necessary to move the edit target part to an appropriate screen position.
Even when the editing work is performed at a plurality of places, this series of work is required every time the screen operation is performed, which lowers the work efficiency.

[0013]

When the display state of the drawing is changed depending on the magnification and the position, in order to obtain the target display state, the magnification or the range of the display place is specified.
It is necessary to perform screen movement processing after changing the screen scale, and when editing work is performed in parallel in multiple parts, it is impossible to display the same screen state in one operation.

The present invention has been made to solve the above problem, and allows an operator to select one side of an element for design reference and secure the coordinates of both end points thereof. Furthermore, by locating on the 2-point screen after selection, the end points of one side can be changed to the display that allows the player to reach the locate position, thereby improving the operability of the enlargement / reduction display and simplifying the operation for specifying the screen display position. To do.

[0015]

According to the present invention, both end points for grasping the positions of the end points of the element selected by the worker in order to allocate the end points of the selected element to two points on the screen newly located by the worker. It is a graphic processing device newly provided with a position income part, a two-point distance acquisition part for measuring a distance between two points, and a locate position acquisition part for locating a locate point to which an end point of an element is assigned.

[0016]

According to the present invention, when the screen display is changed by the above configuration, the setting of the enlargement / reduction ratio and the input of the moving distance, which are carried out each time, are omitted, and the batch processing of the magnification change and the position change is realized. The operability of display is improved.

FIG. 2 is a flow chart of the graphic processing apparatus in one embodiment of the present invention. The screen display method in assigning both end points of the selected element will be described below.

First, an operator selects one side of an element to be used or referred to for designing (S1).

The position coordinates of both end points of the selected element are acquired (S2). In addition, after obtaining the position, the lengths of both end points are calculated (S3).

Next, two points to which both end points of the selected element are assigned are located (S4). The distance between the two located points is calculated (S5).

A magnification is calculated using the distance between the two-point locate and the distance between both end points of the element selected first (S6).

Further, the moving distance and the moving direction are calculated using the coordinates of both end points of the selected element and the coordinates of the two locate points (S7).

A screen display is performed based on the information calculated in steps 6 and 7 (S8). The above process will be specifically described with reference to FIG.

It is a figure showing the state where the movement of the display was completed.

First, in FIG. 3A, the operator selects one side of an element of interest. Both end points of the selected side are p1 and p2. Next, as shown in FIG. 3B, p
Locate two points where you want to allocate 1 and p2. The locate points are set to 15 and 16. When the locate information is obtained, the system calculates the magnification, the moving distance, the direction, etc., and changes the screen to allocate p1 to locate point 15 and p2 to locate point 16. FIG. 3C shows the final screen display state.

[0028]

As described above, according to the present invention, both end points of the selected element are newly allocated to two points on the screen which the operator locates, thereby specifying the magnification, inputting the screen movement distance, and displaying the intended screen. It is to reduce the burden on the worker of repeating the operations up to and improve the operability of the screen display for realizing the screen of the magnification and the positional relationship intended by the worker in one operation.
