It keep the ratio between cooper and empty space the same with growing clearance. There is completly different story with the rounded ones..those get worser with growing clearance. But I have no idea how to do the math correctly(I am into discrete math, not geometry :-(( ). > Aside from this, there are still some problems - the ArcPoly function > doesn't appear to do very well for geometries where the hemispherical > caps around the end of the arc intersect with each other. I don't remember exactly, but when I was investigating the crash I found problem in some function calculating intersections. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
