Is there an equivalent to CurveBoolean Rhino command in RhinoCommon?
Probably not, but what would be an approach to select bunch of curves and by point that is inside some region create a closed outline? For Polylines I used Clipper library, but not for curves.
RhinoCurveBoolean has been added to the C++ SDK as of SR12. It’s a little complicated since it returns the information necessary to construct the results as nested lists of subdomains of the input curves. We’re trying to decide how best to present this in RhinoCommon.
