How can I make open polysurface to closed polysurface or solid in grasshopper?

You uploaded only a 3dm file, is this a Rhino or a Grasshopper question?

Grasshopper question. I am trying to create those items in tekla through grasshopper live link plugin.

I am able to create solid items in tekla via grasshopper link. see below


The brep simply has naked edges:

Just exploding and rejoining the brep takes care of almost all of them, you’ll be left with two naked, very short edges. They are far shorter (0.000623 millimeters) than the absolute tolerance of your model, which is problematic in itself. By lowering the tolerance, then exploding and joining again I managed to get that down to just two naked points instead, but this is where my knowledge of brep-fixing comes to a screeching halt.

I think you’ll have to ask on the regular Rhino category how to fix this and then maybe we can see whether or not such an approach can be mimicked in Grasshopper.

FWIW, testRemoveNakedMicroLoops will remove these 2 naked remaining naked edges.


Its not working in Rhino 5
Command: TestRemoveAllNakedMicroLoops
Removed 0 edges from 0 polysurface.

Working in Rhino 6 Beta
Command: RemoveAllNakedMicroLoops
Removed 2 edges from 1 polysurface.

Thank you for your great reply.
