I’m trying to create detail lines based off geometry in a CAD link. I would like it to basically work like pick line tool.
One issue I’m running into is getting different type of geometry and trying to pull useable data out of them to us with the doc.Create.NewDetailCurve method. Is there a simpler way to do this than having different workflows for arc, polylines, and lines?
I’m starting with the PolyLine class, but can’t seem to get curves from it, only coordinates and I don’t think that is enough to make accurate lines.
For arcs it looks like I could get radius, center getendpoints which would probably be enough.
