Abstract

PURPOSE:To easily and correctly determine a coordinate position by moving the displaying position of a coordinate scale to a position whose origin is the coordinate position corresponding to coordinate data inputted just now every time the coordinate data of a pattern is inputted, and providing the position for the input of the next coordinate data. CONSTITUTION:When the coordinate data of a moving destination is inputted by a keyboard 8 while a system is kept in a state that the manual movement mode of the coordinate scale is designated, a coordinate scale manual movement control means 12 moves the displaying position of the coordinate scale on a display device 9 to the position whose origin is the coordinate position corresponding to the coordinate data of the moving destination inputted just now. Thus, at the time of determining the next coordinate position, the moved coordinate scale can be used as the origin as it is, and thus, the new coordinate position can be easily and correctly determined.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Fields] The present invention is applicable to, for example, CA D (Coa+puter A
The present invention relates to a coordinate scale display method for displaying a coordinate scale on a display screen in order to assist graphic input operations in an IDEDesign system.

[Prior Art] Generally, in a CAD system, an operator moves a cursor while looking at a display screen such as a CRT display, and when the cursor has moved to a desired position, the coordinates are determined by operating, for example, an "execute/select key". The data is determined and a desired figure is created on the display screen. Therefore, in order to efficiently create a figure, how to determine the coordinate position becomes an important issue.

Conventionally, for example, grid points or grid-shaped input auxiliary lines are displayed on the entire display screen, and the coordinate position of a figure is determined based on the intersection of these grid points or input auxiliary lines, or a coordinate scale is displayed on the display screen. It is displayed in a fixed manner, and the coordinate position of the figure is determined by referring to the scale attached to this coordinate scale.

[Problems to be Solved by the Invention] However, with this conventional method, ■ Grid points and input auxiliary lines are always displayed on the entire display screen, which may make it difficult to see the figures displayed on the display screen. There is.

■ Since the coordinate scale is displayed in a fixed manner, it becomes difficult to refer to the scale of the coordinate scale when creating a figure at a position far from the display position of this coordinate scale.
As a result, the efficiency of producing figures becomes low.

There were some issues that needed to be improved.

Therefore, the present invention focuses on the above-mentioned circumstances, and provides a coordinate scale display method that allows the coordinate scale to be used effectively at all times, thereby making it possible to easily and accurately determine the coordinate position, thereby increasing the efficiency of figure creation. The purpose is to provide.

Another object of the present invention is to provide a coordinate scale display method that allows figures of any length and direction to be created easily and accurately.

Still another object of the present invention is to provide a coordinate scale display method that allows the initial position of the coordinate scale to be arbitrarily set, thereby making it possible to easily determine the initial coordinates of a figure.

[Means for Solving the Problems] The present invention provides a system in which a coordinate scale having graduations is displayed on a display screen and a figure is input by referring to this coordinate scale. In response to this input operation, the display position of the coordinate scale is moved to a position whose origin is the coordinate position corresponding to the currently input coordinate data, and is used for inputting the next coordinate data. .

In another aspect of the present invention, each time coordinate data of a figure is input, the display position of the coordinate scale is moved to a position whose origin is the coordinate position corresponding to the currently input coordinate data in response to this input operation. In addition to inputting the next coordinate data, the scale interval and rotation angle of the coordinate scale being displayed can be entered, and the display pattern of the scale corresponding to the input scale interval is displayed superimposed on the coordinate scale. , the display position of the coordinate scale is rotated around the origin in accordance with the rotation angle.

Still another aspect of the present invention is provided with a movement mode finger/foot means for specifying whether the display position of the coordinate scale is to be moved automatically or by manual operation, and the movement mode specifying means specifies the automatic movement mode. In this state, each time the coordinate data of the figure is input, in response to this input operation, the display position of the coordinate scale is changed to a position whose origin is the coordinate position corresponding to the coordinate data of the figure that has just been input. On the other hand, when the manual movement mode is specified by the movement mode specifying means, this input operation is performed every time the coordinate data of the destination of the coordinate scale is input. In response, the display position of the coordinate scale is moved to a position whose origin is the coordinate position corresponding to the coordinate data of the destination that has just been input.

[Function] As a result, according to the present invention, each time coordinate data of a figure is input, the display position of the coordinate scale automatically moves to follow the currently input coordinate position, so that the next coordinate position can be adjusted. When determining , the moved coordinate scale can be used as it is as the origin, thereby making it possible to easily and accurately determine a new coordinate position.

Therefore, the efficiency of graphic creation can be greatly increased compared to the case where the coordinate scale is fixedly displayed.

According to another aspect of the present invention, in addition to the automatic movement function of the coordinate scale described above, it has a function of variably setting the scale interval and angle of the coordinate scale, so that the distance and direction to the next coordinate position can be adjusted. By inputting the scale interval and rotation angle of the coordinate scale accordingly, the scale interval and rotation angle of the coordinate scale can be changed as appropriate. therefore,
Even when the distance and direction change, it becomes possible to efficiently determine the next coordinate position by using the coordinate scale as is.

According to still another aspect of the present invention, in addition to the automatic coordinate scale movement mode, the coordinate scale manual movement mode is provided, so that the initial position of the coordinate scale can be arbitrarily set manually. The initial coordinates of a figure can also be easily determined.

[Embodiment] FIG. 1 is a schematic configuration diagram of a CAD system to which a coordinate scale display method is applied in an embodiment of the present invention.

This system has a control unit (CPU) 1, and this CPU
A database 5 consisting of a program ROM 3, a data RAM 4, and an external storage device is connected to the UI via a bus 2. The program ROM 3 stores in advance various control programs necessary for creating graphics. The data RAM 4 stores coordinate data and the like that need to be temporarily stored during graphic creation.

The database 5 stores in advance various data such as display patterns necessary for creating graphics.

Furthermore, a keyboard interface 6 and a display interface 7 are connected to the CPU via a bus 2, respectively. A keyboard 8 is connected to the keyboard interface 6, and data input by the keyboard 8 is taken into the CPUI via the keyboard interface 6. On the other hand, a display device 9 consisting of a CRT display is connected to the display interface 7.
Display data output from the UI or the like is supplied to the display device 9 via the display interface 7 and displayed.

By the way, the CPUI is composed of, for example, a microcomputer, and its control functions include, in addition to the normal control means used to create figures, a coordinate scale automatic movement control means 11 and a coordinate scale manual movement control means 1.
2 and a coordinate scale change control means 13.

The coordinate scale automatic movement control means 11 controls the keyboard 8 when the coordinate scale automatic movement mode is specified.
When the coordinate data of a figure such as the start point coordinate and end point coordinate of the figure is input, the display position of the coordinate scale on the display device 9 is set to the position whose origin is the coordinate position corresponding to the coordinate data of the figure that has just been input. It is meant to be moved.

The coordinate scale manual movement control means 12 controls the keyboard 8 when the coordinate scale manual movement mode is specified.
When the coordinate data of the destination is input by , the display position of the coordinate scale on the display device 9 is moved to a position whose origin is the coordinate position corresponding to the coordinate data of the destination that has just been input.

The coordinate scale change control means 13 changes the scale display of the coordinate scale according to the scale interval and the rotation angle when data on the scale interval and rotation angle of the coordinate scale is inputted from the keyboard 8. This rotates the display position of the coordinate scale around its origin.

Next, the coordinate scale display method of this embodiment will be explained based on the above configuration.

First, a case will be described in which the automatic movement mode is set and a figure is input.

When you start the figure creation process, the CPU will be displayed as shown in Figure 4 (
As shown in a), in step 4a, the preset initial values of the scale interval and rotation angle are recognized, and in accordance with these data, the initial pattern of the coordinate scale is displayed on the display device 9 in step 4b. In addition, as initial data of the scale interval and rotation angle, for example, scale interval - 1 degree rotation angle -
Set to 0°. FIG. 2(a) shows an example of the initial display result of the coordinate scale in this case.

In this state, the CPU determines whether the movement mode is set to automatic movement mode or manual movement mode (step 4c), and determines whether a coordinate scale change input has been made (step 4c). 4d) and determining whether or not the starting point coordinate data of the figure has been input (step 4e) are repeatedly performed. In this state, for example, the operator moves a cursor (not shown) to the
Assume that the user moves to Pl in a) and performs a finalization operation using this Pl as the starting point coordinates. Then, CPU1 performs step 4e.
The process moves to step 4f, where the input start point coordinate data is temporarily stored in the RAM 4, and then the process proceeds to step 4f.
Delete the old coordinate scale with g and step 4h
Then, as shown in FIG. 2(b), a new coordinate scale is displayed with the starting point coordinate P1 as the origin. Therefore, the coordinate scale automatically moves to the starting point coordinate position.

Then, when the starting point position coordinates are input, the CPU 1
As shown in Figure (b), it is repeatedly determined whether a coordinate scale change input has been made (step 4i) and whether the end point coordinate data of the figure has been input (step 4j). In this state, the operator moves 10 degrees diagonally upward to the right by 30 degrees from the starting point coordinate P1, for example.
．． Assume that data for changing the scale interval and rotation angle is input in order to draw a straight line with a length of 5 mar. Then, C.P.
The UI executes coordinate scale change control. That is,
As shown in FIG. 6, the scale interval and rotation angle data inputted from the keyboard 8 in step 6a are imported via the keyboard interface 6, and the RA data is inputted in step 6b.
The initial data of the scale interval and rotation angle previously stored in M4 is rewritten with the newly input data.

Then, in step 6C, the display position of the new coordinate scale is calculated, and in step 6d, this new coordinate scale is displayed. For example, in order to draw a straight line with a length of IO, 5 cm from the position of the starting point coordinate P1 diagonally upward and to the right by 30 degrees as described above, the scale interval -2,11 rotation angle -30'' is input. In this case, the display device 9 displays a message as shown in FIG. 2(e).
2.1 A scale is displayed at a pitch of av, and a coordinate scale rotated by 30 degrees around the origin is displayed.

In this state, it is assumed that the operator moves the cursor along the X-axis of the coordinate scale to the fifth division position P2 corresponding to IO, 5 ms, and performs an operation to confirm the end point coordinate data at this position P2. Then, the CPU 1 moves from step 4j to step 4k, stores the end point coordinate data in the RAM 4, and then, in step 41, displays a straight line from the starting point P1 to the ending point P2 as shown in FIG. 2(d). After the CPU 1 erases the old coordinate scale in step 4m, the CPU 1 erases the old coordinate scale in step 4n.
), a new coordinate scale whose origin is the end point coordinate P2 is displayed.

Thus, a straight line figure between Pl and P2 is input to the system.

Next, a case will be described in which a figure is input using the automatic movement mode and the manual movement mode, respectively.

For example, after completing the input of the straight line figure L1 as shown in FIG. 3(a), continue to input the straight line figure L2 as shown in FIG.
When inputting , first, the movement mode of the coordinate scale is switched from automatic movement mode to manual movement mode by operating the keyboard 8. Then, the CPU determines in step 4C that the movement mode is set to manual mode, and thereafter executes manual movement control.

That is, as shown in FIG. 5, the CPU first determines whether or not a coordinate scale change input has been made (step 5a).
) and determining whether the destination coordinate data has been input (
Step 5b) is then repeated. Then, in this state, it is assumed that the operator moves the cursor, for example, by five scales along the Y axis of the coordinate scale, and performs an operation to confirm the movement destination at this position po. Then, the CPU moves from step 5b to step 5C, where the destination coordinate data P is obtained. After storing in the RAM 4, the old coordinate scale is deleted in step 5d, and the destination coordinate P is stored in step 5e. Display a new coordinate scale with the origin at . Therefore, the display device 9 displays P as shown in FIG. 3(b). A coordinate scale with the origin at is displayed.

Next, when the operator moves the cursor to the 5th scale along the X-axis of the coordinate scale and confirms the destination at this position P1, the CPU 1 selects the destination in step 5C as in the case of P0 above. The coordinate data P1 of
4, the old coordinate scale is erased in step 5d, and a new coordinate scale whose origin is P is displayed in step 5e, as shown in FIG. 3(C).

In this way, the movement of the display position of the coordinate scale by manual operation is completed.

Next, it is assumed that after switching the movement mode to automatic movement mode, the operator moves the cursor three scales along the Y axis of the coordinate scale, and performs an operation to confirm the coordinate data using this position P2 as the starting point. Then, the CPU temporarily stores the starting point coordinate data P2 in the RAM 4 in step 4f, erases the old coordinate scale in step 4g, and displays a new coordinate scale at the position whose origin is the starting point coordinate P2 in step 5h. . Thus, the display position of the coordinate scale is automatically moved to the starting point coordinate position as shown in FIG. 3(d).

In this state, when the operator inputs rotation angle data to rotate the coordinate scale by, for example, 30'', the CPU
As in the case of FIG. 2(C) described above, rotation control of the coordinate scale is performed according to FIG. 6. Therefore, the coordinate scale being displayed is rotated by 30 degrees around the starting point coordinate P2 as shown in FIG. 3(e). Then, in this state, when the cursor is moved 4 divisions along the X-axis of the coordinate scale and the coordinates are confirmed with this position P3 as the end point position, the CPU A straight line figure L2 from the starting point P2 to the ending point P3 is displayed, and then, in step 4m, the old coordinate scale is erased, and in step 4n, a new position is displayed with the ending point coordinate P3 as the origin, as shown in FIG. 3(f). Display the coordinate scale. In this way, the straight line figure L2 is input at a position spaced apart from the straight line figure L1.

In the above description, both when inputting the coordinate position of a figure and when inputting the coordinate position of a destination, the input is performed at a position on the axis of the coordinate scale and coincident with the scale.

However, depending on the operation, the input position may deviate from the scale position on the axis of the coordinate scale. Therefore, the CPUI of this embodiment sets a predetermined input permissible area for each scale position of the coordinate scale, and even if the input coordinate position slightly deviates from the scale position on the axis of the coordinate scale, the input permissible area is If it is within the range, the input data is assumed to have been made at the regular scale position and the figure is created. On the other hand, if the input position is outside the input permissible area, it is determined that it is an erroneous input and the input is discarded.

As described above, in this embodiment, if the movement mode of the coordinate scale is set to automatic movement mode, when the start point coordinates and end point coordinates of a figure are input, the display position of the coordinate scale will be set to these coordinate positions. will be automatically moved to the position where the origin is. Furthermore, by inputting data on the scale interval and rotation angle of the coordinate scale at each point, the pitch of the scales displayed on the coordinate scale and the angle of the coordinate scale can be arbitrarily changed. Therefore, when inputting a continuous figure by specifying the start point and end point one after another, such as a continuous polygonal line figure, it is easy to determine the coordinates of each start point and end point by using the scale of the coordinate scale as is. Moreover, it can be done quickly and accurately, thereby greatly increasing the efficiency of graphic creation.

Furthermore, when the manual movement mode is set, when the destination coordinates of the coordinate scale are input, the display position of the coordinate scale is moved to the destination coordinate position. Therefore, the operator can arbitrarily and easily set the initial position of the coordinate scale regardless of the graphic input.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, a case has been described in which the coordinate scale can automatically move only along its axis in the automatic movement mode, but it may also be possible to automatically move in any direction other than the axial direction.

Further, in the above embodiment, the case of a coordinate scale or a two-dimensional scale consisting of an X-axis and a Y-axis was explained as an example, but for example, as shown in FIG. It can be implemented similarly in other cases.

Furthermore, the display color and display density of the coordinate scale may be made different for each axis or for each region on the same axis.

In addition, the configurations, control procedures, control contents, etc. of the automatic movement control means, manual movement means, and coordinate scale changing means can be implemented in various ways without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, the present invention responds to the input operation to change the display position of the coordinate scale to the coordinate position corresponding to the coordinate data that has just been input, every time the coordinate data of a figure is input. The coordinate data is moved to the origin and used for inputting the next coordinate data.

Therefore, according to the present invention, it is possible to always use the coordinate scale effectively, and thereby the coordinate position can be easily and accurately determined.
It is possible to provide a coordinate scale display method that can improve graphic creation efficiency.

In another aspect of the present invention, each time coordinate data of a figure is input, in response to this input operation, the display position of the coordinate scale is moved to a position whose origin is the coordinate position corresponding to the coordinate data that has just been input. In addition to inputting the next coordinate data, the scale interval and rotation angle of the coordinate scale being displayed can be entered, and a scale display pattern corresponding to the input scale interval is displayed superimposed on the coordinate scale, The display position of the coordinate scale is rotated around the origin in accordance with the rotation angle.

Therefore, according to this other aspect of the present invention, it is possible to provide a coordinate scale display method that can easily and accurately create figures of any length and direction.

Still another aspect of the present invention is provided with a movement mode specifying means for specifying whether the display position of the coordinate scale is to be moved automatically or by manual operation, and the automatic movement mode is specified by the movement mode specifying means. In this state, each time the coordinate data of the figure is input, in response to this input operation, the display position of the coordinate scale is changed to a position whose origin is the coordinate position corresponding to the coordinate data of the figure that has just been input. When the manual movement mode is specified by the movement mode specifying means, each time the coordinate data of the destination of the coordinate scale is input, the system responds to this input operation. Then, the display position of the coordinate scale is moved to a position whose origin is the coordinate position corresponding to the coordinate data of the destination that has just been input.

Therefore, according to this other aspect of the present invention, it is possible to provide a coordinate scale display method that allows the initial position of the coordinate scale to be arbitrarily set and allows the initial coordinates of a figure to be easily determined.
