Abstract

PURPOSE:To simply attain automatic generation by providing a means storing the coordinate and the radius of a reference point into a memory device and a means assinging the same symbol to the same radius and describing the result so as to express the radius of a circular-arc by a symbol in a detailed drawing. CONSTITUTION:In generating a circular-arc in a drawing, an input means 52 applies the limit designation of describing the radius of circular arc and not describing it. Then in a means 53 storing the result to the memory device, while the radius of the circular arc of a designated value or over is described and as to the circular arcs less the designated value, the reference point coordinate and the radius are stored in the memory device. Then in a symbol assignment and describing means 54, the same symbol is assigned to the same radius and the symbol is described in the vicinity of the part of a prescribed detailed drawing. Then the consecutive part of the circular arc below the designated value to complete the detailed drawing, is found out, the enlarged drawing of the part is formed and the layout and the marking of the discovered part are applied. Thus, the radius of the circular arc is expressed by the symbol in the detailed drawing and the drawing is generated automatically simply.

Description

[Detailed Description of the Invention] [Summary] In a two-dimensional detailed drawing creation method in which dimensions are written on arcs with large radii, symbols are written on arcs with dimensions less than a predetermined value in order to make the drawings easier to read. This method allows you to easily create concise drawings.

[Industrial Field of Application] The present invention relates to a method for automatically creating detailed two-dimensional drawings in a concise manner.

Conventionally, when creating a detailed drawing of a cutting edge portion of a precision mold, a large number of man-hours are required, and detailed dimensions are written on the drawing, making it difficult to see. Therefore, there was a need to develop a method for automatically creating easy-to-read drawings in a short time.

[Prior Art] In fields such as mechanism design and mold design, precision molding is used to manufacture lead frames and connectors for integrated circuits, which are characterized by drawings with detailed dimensions of specified shapes. In the mold, all corners of the cutting edge are rounded for strength and precision.
It is necessary to create many detailed drawings for such cutting edge parts. Therefore, a processing method that automatically creates drawings with dimensions for two-dimensional figures, especially figures consisting of line segments and circular arcs, by computer processing is, for example, to extract all the coordinate values, rearrange them, and then move the coordinate dimensions in the left, right, top, and bottom directions. At the same time, you can write the radius dimension for the arc part that exceeds the internal range, or you can use the specific point of the figure as a reference and write the dimension in the form of a leader line in the X direction and Y direction, respectively. be. The former method is illustrated in the block diagram of FIG.

In Figure 7, DB is a database of characters and figures,
DBS refers to a database system; otherwise refers to a means for automatically filling in coordinate values and radial dimensions for figures in a database. In the automatic filling method, step ■
Now enter the minimum radius value for writing the radius dimension of the circular arc, the magnification of the figure, and the coordinates of the reference point. Next, in step (2), the coordinate values of the two-dimensional figure are extracted. In step (2), the values of the coordinates on the X axis are rearranged in ascending order.

In step (2), the Y coordinate values are similarly sorted in ascending order, and in step (2), data obtained in step (2) are processed to remove data having the same Y coordinate value. In step (2), data having the same X coordinate is removed. In step (2), sorting is performed in ascending order of Y coordinate. In step (2), sorting is performed in ascending order of the X coordinate value. In step (2), coordinate values and dimensions are written for the figure enlarged or reduced by the specified magnification. Next, in step [phase], the radius dimension is entered, and in step (2), the input figure is enlarged or reduced. Enter the reference line in step @.

FIG. 8 shows an example of a graphic processed using the block diagram shown in FIG. In Figure 8, the line (a) is the center line, the line (bl) is the coordinate value dimension line, and the line (a) is the coordinate value dimension line.
The line (C) is the radial dimension line drawn in step 0 of FIG.

FIG. 9 shows a figure similar to that shown in FIG. 8, and is an example in which dimensions are not entered for a circular arc having a specified radius or less.

[Problems to be Solved by the Invention] As shown in Figure 9, when dimensions are not entered in areas with rounded corners, etc., the designer checks the shape later and fills in the missing areas with dimensions. or add symbols. Or, since it is essential to add partially enlarged drawings, the detailed drawings that have been automatically processed and output are further
It had to be edited using an AD system or added by hand, which had the disadvantage of poor design efficiency.

In addition, as shown in Figure 8, if radius dimensions are automatically entered for all arcs, such as those with rounded corners, leader lines or dimension lines will be added to the finished drawing. This has the disadvantage that the drawings become very difficult to read because many mutual interferences and overlaps occur, such as line segments of figures. Further CA
When inputting the shape of the cutting edge part after rounding the corners in the D system, if the cutting edge had a small difference, but was lost as a result of the rounding,
Later, a problem arose in that the dimensions of this stepped portion could not be entered in detailed drawings.

An object of the present invention is to improve the above-mentioned drawbacks and provide a method for automatically creating even detailed drawings in a simple manner by expressing the radius of an arc with a symbol.
