Edge Seam Templates

Sometimes, the short edges of a plate are not located in frame plane. Since the position of the templates described in this Appendix always are decided by the frame positions a rather big plate area may be left uncovered by any template. Therefore there is an option to get additional templates parallel to the short edges of the plate. These templates are called edge seam templates.

The edge seam templates are requested by an IP with at most two parameters:

EDGE_SEAM_TEMPLATES, [<angle>, [<distance>,] ]

To get these extra templates there must be a certain deviation from 90 degrees in the angle between the short and long edges. This angle is by default 75 degrees but any value may be given by the customer (=<angle>).

The templates will be placed roughly parallel to the short edges of the plate between two points at a given distance from the corners. The distance is measured along the upper and lower seams. The default distance is 100 but the customer may specify any value (=<distance>).

Edge seam templates in association with normal templates will be perpendicular to the same base plane as the other templates.

For edge seam templates in combination with frame templates the planes of the edge seam templates will be perpendicular to a base plane. This base plane is perpendicular to the sight (line) plane and contains the sight line (at height about 600 mm), that means, is roughly parallel to the plate.

If the butts at the short edges (the base seams) lie in a frame plane no edge seam will be created at the respective butt.

If there should be an interference between an edge seam template and the closest templates in a frame position, the frame templates will be deleted.
