Both Rhino.Geometry.Brep.CreateContourCurve() methods fail in v7 but not in v6. Does not seem dependent on the input. Minimal example using rhinoscriptsyntax, but I’ve tried the core functions as well.
import Rhino import rhinoscriptsyntax as rs if __name__ == "__main__": sp_id = rs.AddSphere( Rhino.Geometry.Plane.WorldXY, 10 ) rs.AddSrfContourCrvs( sp_id, Rhino.Geometry.Plane.WorldXY )
(For anyone hitting this issue, Rhino.Geometry.Intersect.Intersection.BrepPlane() is working as expected.)
