Abstract

PURPOSE:To quickly confirm and correct the layout state of a designated form by displaying rectangular frames indicating the size of the drawn form in designated positions. CONSTITUTION:When the layout method and the layout condition of a form 5 are inputted by a keyboard 1 and the name of the form 5 is inputted, dimensions of the rectangular frame inscribed to the form are calculated, and 8 rectangular frames 6 are radially displayed on the screen of a display device 3. When an operator gives an indication from the keyboard 1, the form 5 whose name is inputted is displayed in the position where each rectangular frame 6 is displayed. Thus, overlapping or the layout positions of respective forms are conformed, and forms can be quickly drawn again at the time of correction because the drawing data volume is small. Consequently, the work efficiency of form layout data for laser working or the like is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shape drawing device that creates processing data and the like by arranging various independent drawn shapes at desired positions using a CAD system or the like.

[Conventional technology]

Conventionally, a shape drawing device used to create processing data for making many molds of the same or different shapes from one sheet of material without waste by laser processing, NC processing, etc. Kosho 61-4148
As seen in the above publication, when an operator selects a desired shape from a group of various shapes displayed on a portion of the display device and specifies its placement position, the computer automatically selects the optimal display position. There was something I could do to make it appear.

Furthermore, as seen in Japanese Patent Application Laid-Open No. 63-61305, if you specify a shape to be drawn and then specify a drawing interval for that shape, the number of shapes that can be placed in the drawing area is calculated, and along with that number, Some displayed the selected drawing shape.

[Problem to be solved by the invention]

However, these conventional shape drawing devices all draw and display the shape specified by the operator at the placement position, so if the drawn shape is complex (including non-circular curves, etc.) Because the amount of data was large, it took a long time to draw.

If the operator is not satisfied with the arrangement (for example, one interval is too long or the shape overlaps with a previously placed shape), the operator corrects the position of the shape and draws it again. Since it has to be redone, it takes a lot of time each time, and there is a problem that the efficiency of creating shape layout data is low.

This invention has been made in view of the above points, and it is an object of the present invention to improve the efficiency of creating shape arrangement data by making it possible to quickly check and correct the arrangement state of a specified shape using the shape drawing device described above. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a shape layout designating means A for designating the types of independent drawing shapes and their placement positions, as shown in the functional block diagram in FIG. and shape drawing means C that draws the specified shape at a specified arrangement position and displays it on the screen of display device B. a rectangular frame dimension calculating means for calculating the dimensions of a rectangular frame to be drawn, and a rectangular frame for displaying the rectangular frame having the calculated dimensions at the arrangement position specified by the shape arrangement specifying means A on the screen of the display device B. It is provided with a drawing means E and a drawing switching means F for selectively enabling either the shape drawing means C or the rectangular frame drawing means E.

[For production]

In the shape drawing device according to the present invention, when the shape arrangement specifying means A specifies the type of independent drawing shape and its arrangement position, the shape drawing means C displays it on the display! However, when the drawing switching means F switches to display a rectangular frame, the rectangular frame drawing means E draws a rectangular frame circumscribing the shape specified by the dimensions calculated by the rectangular frame dimension calculating means. is displayed quickly instead of the specified shape.

Therefore, the arrangement state of the shape specified by the operator can be easily confirmed, and even if correction is required, the amount of data is small, so redrawing can be performed in a short time.

〔Example〕

Hereinafter, embodiments of the present invention will be specifically described based on the drawings from FIG. 2 onwards.

FIG. 2 is a block diagram of a shape drawing device that is an embodiment of the present invention.

This shape drawing device has a keyboard 1. Processing device 2, display device 3. and a storage device 4.

Keyboard 1 is for letters, numbers, and cursor movement.

Equipped with various keys such as function selection, input of various character data, selection of drawing shape type and specification of its placement position 9
Controls the specification of arrangement methods such as rotational arrangement and individual arrangement, the input of the rotation angle for two-rotation arrangement, and the input of various other instructions.

That is, the keyboard 1 is the shape layout designating means A of FIG.
fulfill the role of

The processing device 2 is a microcomputer equipped with a CPU, RAM, ROM, etc., and is in charge of controlling the entire device, and also performs processing to calculate the dimensions of a rectangular frame circumscribing a specified shape, and performs processing of the calculated dimensions. It handles the process of drawing a rectangular frame at a designated position on the screen of the display device 3, the process of reading out various independent shapes stored in the storage device 4 and displaying them on the screen of the display device B, etc.

That is, it functions as the shape drawing means C, the rectangular frame dimension calculating means, and the rectangular frame drawing means E shown in FIG.

The display device 3 is a display device such as a CRT or an LCD, which corresponds to the display device B in FIG. and display various messages, etc.

The storage device 4 is a storage device such as a hard disk device, and stores various independent drawing shapes, and also stores data of an entire image in which a large number of specified shapes are arranged.

Next, FIG. 3 is a flowchart showing a process of displaying a rectangular frame and an actually designated shape by the shape drawing device of FIG.

When the operator specifies the arrangement method and arrangement conditions (placement position, 2 rotation angles, etc.) of the shape to be drawn using the keyboard 1 and inputs the shape name, the height of the rectangular frame circumscribing the shape of the input shape name is - Calculate the horizontal dimension from, for example, the maximum and minimum values of the X and Y coordinates of the specified shape in the selected display area.

Then, based on the dimensions, the rectangular frame is displayed at the designated position on the display screen of the display device.

After that, if the operator gives an OK instruction, the actual specified shape to be drawn (actual shape) is displayed instead of a rectangular frame, and if the operator gives a No instruction, the process returns to inputting the layout method and corrects the input data. The above processing is repeated, and when an OK instruction is input, all processing ends.

In addition, when calculating the dimensions of a rectangular frame, if you read the maximum and minimum values of the XY coordinate values of the specified shape and calculate the vertical and horizontal dimensions of the rectangular frame from those coordinate values, the rectangle will be , the maximum X at which the specified shape lies on the coordinate plane
It is a rectangle whose diagonal points (two vertices connected by a diagonal line of the rectangle) are the point of the coordinate value and yl reference value and the point of the minimum X and Y coordinate values.

Next, a display example of a shape drawn by this shape drawing device and an operation procedure at that time will be explained.

First, FIG. 4 is a diagram showing an example of a shape displayed on the display screen of the display device 3 by the operator.

The operator first specifies rotational arrangement as a shape arrangement method using the keyboard 1, and inputs, for example, the arrangement position, center point (coordinate values), and rotation angle θ=45° as arrangement conditions.

Then, when the name of shape 5 shown in FIG. Na(
Eight rectangular frames 6 are drawn and displayed clockwise or counterclockwise on the rays at intervals of θ=45°.

Therefore, when the operator checks the arrangement status and determines that the current arrangement position is fine and inputs an OK instruction from the keyboard 1, the shape 5 for which the name has actually been input is displayed in each rectangular frame 6 in FIG. Draw each at the displayed position and
Display as shown.

Note that the rectangular frame 6 in the example 2 is drawn with a size that inscribes the shape 5, but as shown in FIG. Alternatively, it is convenient to draw a rectangular frame 8b with a margin shown by a dashed-dotted line, since it is possible to take into account the overlapping margin between shapes.

[Effects of the Invention] As explained above, according to the shape drawing device of the present invention, when specifying a drawing shape and placing it at a specified position, first a rectangular frame representing the size of the shape is placed at the specified position. Since it is displayed, it is possible to check the presence or absence of mutual overlap between the shapes and their arrangement positions, and if it is desired to correct it, the drawing data can be quickly redrawn since the amount of drawing data is small.

Therefore, the efficiency of creating shape layout data for laser processing etc. can be improved.
