Seam Crossing Hole

If a seam is defined across a hole, the designer has the possibility to state that the hole should be 'opened' with a predefined distance. In the drawing the hole will be presented with a gap for the seam. The hole can also be divided into two with a bridge for the seam.

When ppanparts is run, the hole is not included in the plate boundary. Instead the hole will be opened up and stop at a predefined distance from the plate edge. This part is available for cutting.

A default keyword MARK_HOLE_PART in the IP file for ppanparts controls the minimum distance from the hole edge to the plate edge. If the distance between the two edges is less than specified in the keyword, the part of the hole will be treated as a marking.

If the hole is larger than a by the user specified size, the hole will be opened in the middle of the cut contour.
