BobD Posted December 21, 2005 Share Posted December 21, 2005 Hello All, I am trying to build a polyline which represents the outline of a segment top door. It is composed of an arc and three lines. I need to take this polyline object and do an intersect suface against a grid of windows to then create a segment top window grid. I am creating the arc with arcbycenter and cannot find a way to create one polyline object with the four pieces. I have tried to do an addsurface of the arc, but it seems that arcbycenter does not create an object from which I could grab a handle. The only vw arc command which creates a polyline is arcto, but I don't how to algorithmically calculate control points. Any ideas out there? Thanks, BobD Quote Link to comment

ccroft Posted December 22, 2005 Share Posted December 22, 2005 Hey Bob, I was able to get a handle to the arcbycenter with LActLayer. LNewObj didn't work though. Charles Quote Link to comment
BobD Posted December 22, 2005 Author Share Posted December 22, 2005 Andrew - thanks for the suggestion. I did a little research on NURBS and ended up calculating the necessary control point locations and then used ArcTo. This resulted in the polyline object I needed. Bob D. Quote Link to comment

Vectorworks, Inc Employee Andrew Bell@NV Posted December 22, 2005 Vectorworks, Inc Employee Share Posted December 22, 2005 My apologies, I didn't notice this was the VectorScript section, and thus my answer wasn't VectorScript-related.
