Grasshopper

algorithmic modeling for Rhino

Why grasshopper baked untrimmed surface to polysurface?

Can someone help me to understand?
Thanks in advance.

well, thats definitely weird!

I think it is because rhino uses the .Faces.SplitKinkyFaces() method (of brep class) at create RhinoObjects-surfaces. Perhaps the sweep2 of gh should also do it, but it is not the case. As usual, the sweep create perverted surfaces, so... use loft instead.

Here an example more clear:

a polyline is lofted creating an untrimmed surface, if you bakeit, it turns to polysurface as the .Faces.SplitKinkyFaces() does in the next vbscript. So it seems that Rhino uses this method automatically, perhaps there is some reason for wanting to do that.

Hello daniel so you think the only solution is to use the loft in this way?
