Abstract

PURPOSE:To attain an automatic drawing in which a dimension line and a scantling number are not overlapped by providing an interference avoidance processing part consisting of a dimension line drawing direction distribution processing part, a dimension line class selection processing part, a dimension line length calculation processing part, and an area decision processing part. CONSTITUTION:An automatic design program 4 receives an input data 3 and generates a parts data file 5, and a data editing part 6 generates a bit of drawing information by every drawing unit from the data file 5. Next, a dimension line drawing direction distribution processing part 21 at an interference avoidance processing part 2 decides the presence/absence of a dimension line drawing and the drawing direction of a dimension line based on a prescribed selection reference. Following that, a dimension line class is decided at a dimension line class selection processing part 22, and at a dimension line length calculation processing part 23, the position, etc., of the start point, the end point, or the step part of each dimension line by every dimension line class is decided. And finally, it is decided whether all of the dimension lines and scantling numbers are located within a prescribed area where the drawing is set or not at an area decision processing part 24, and an exception process is performed separately when it is overflowed out of the prescribed area. Thereby, the drawing easy to see in which the dimension line and the scantling number are not overlapped can be generated automatically.

Here, the selection base for flower types (for example, holes made in the plate of the mold include holes for passing knockout bottles, holes for passing through id bottles, holes for passing return pins, etc.) depending on the flower type.
Among these, for example, the opening position of the hole through which the bin is passed is predetermined, so if you specify only one position among the multiple holes, you can specify the position of the other holes. This refers to selection criteria such as the ability to omit drawing dimension lines because they are no longer needed. Also,
The selection criteria by hole position is, for example, for a hole drilled in a mold plate, if the hole is located near a specific side, if the dimension line is drawn in the direction of that side, there will be less interference between the dimension lines. This refers to selection criteria such as:

, 5, 60, 0) corresponding to the dimension line drawn out to the Y-axis side of the hole. This dimension line is the same as the -L side dimension line of the rectangular opening located to the left of it, so there is no need to rewrite the coordinate number in the Y-axis direction. All you have to do is draw the lines. Similarly, the dimension line on the right side of this rectangular leap 1-] is at the coordinates (43, 0, 18
, 0), the dimension line of line type d is used because it overlaps with the dimension line drawn out on the XNt side of the hole.
