Hi again. Thank you menno and dale for responding. It’s been awhile since my last post. I send you 3dm test file and some code whit two particular commands. With command SplitBrepFace, after selectin brep and closed curve that lies on the brep, most of the curves on the 3dm file in Rhino5 SR10 return failure because of invalid brep, but in SR9 works fine for all curves.
Also, I find problem with RhinoBrepClosestPoint. See this picture ,
red points are points on curve (drawn with InterpCrvOnSrf command so I suppose that the curve lie on brep). Blue points are obtained from red points by RhinoBrepClosestPoint. In SR9, red and blue points are overlapping. But in SR10, there a cases where blue points are far a way from red ones. You can try the command RhinoClosestPointExampl e from the code that I send you.
Maybe these problems are related?
Please see this example and why we have different behavior with SR’s?
Thanks Filip
