Thanks Lee
Yes I want make points via entmake to all vertex of polyline but if the polyline have a arc-segement (similar bulge T) I want additional point maybe 2 or 3 on all arc-entitties in polyline.
If I translate your function it examines groupcode 42 for bulge more than 0.
What I have to do to can get points on arc. Can I do it with your function or need it more...
