Very simple question: how can I solve for the self-intersection of a polyline with RhinoCommon?
In the attached, I am creating a polyline from a set of points, so it must (as far as I know) be explicitly cast as a polyline and not a curve. Solving for the intersection event with Rhino.Geometry.Intersect.Intersection.CurveSelf returns “Error (CS1503): Argument 1: cannot convert from ‘Rhino.Geometry.Polyline’ to ‘Rhino.Geometry.Curve’”
I’ve found solutions on the forum using RhinoScriptSyntax, but none with RhinoCommon.
I’ve been having a bit of trouble understanding the relationships between all the different geometry types (especially all the Line, Curve, Polyline, Polycurve, PolylineCurve, etc.), but I think I’m starting to get it: because NurbsCurve inherits from Curve, it will work in Intersection.CurveSelf(), but because Polyline inherits from Point3dList it’s incompatible (it’s basically just a representation of a list of points). Please let me know if I have this right…
