Yes, *unless* you're including the start/end angles in that transformation, instead of applying them afterwards. http://www.delorie.com/pcb/tmp/stretched-arc.pcb This shows two 45-degree Arcs. One has width==height, the other does not. Note that the end angle on the stretched arc is 45, but the arc does not end at the 45 degree marker. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
