Bug Rhino7 Mesh.CreateBooleanIntersection

Hi @Ano,

As you assumend, this seems to be a problem with Rhinos internal MeshBooelan Code. Curiously running _MeshIntersect on your two test meshes yields a perfect closed Curve lying on both meshes, so its quite wierd thast the boolean fails. I Tried this in R6, definitely something for @piac to look at as an example for his rewrite of the Mesh Intersection code.

To maybe fix your immediate problem in the meantime:
Since your meshes are rather simple, I would convert them to Polysurfaces via the _ToNurbs command and do the boolean operations on those, as that code is more robust. You can then make a Mesh out of the result again via _Mesh
