Yes, the meshing works, but the mesh goes invalid when I rotate it using a Transform.
Strange that your version of the brep swivel works, but not mine.
If I copy “your” brep into my old GH definition and make a new rotation-transform, no problem occurs, but if I connect the existing transform (created in the same way as my original) the error occurs again if I convert to mesh via a regular mesh parameter, like so:
This is very confusing: the mesh itself seems to not be the main cause of the problem (but if there’s a difference I can imagine it matters how it was imported). The problem for me seems to come from the transform.
The original Transform being chain-linked with many hops from the source Rotation component, but I also tested to connect the source directly to the T-input without any hops, but no difference. The only difference I could find was to make the new rotation component (as in the pictures) and use that one, then the mesh was Transformed with no problem.
I presume you would be interested in my definition, but its huge… The problem was “captured” in the earlier post in which i internalized the transform parameter with its value. If using debug-definition with your version of the brep, does it still produce an invalid mesh? (before dabbling with my massive definition)
But at least the “smooth mesh” does a better job in this case.
