I have collection of solid, closed Brep pipes created by hex arraying an extruded ruled surface:
When I Trim them with a solid Brep formed by extruding a 3D curved Loft surface I get this:
which is what I want - closed Breps.
But SDiff is slow to process, so I thought Trim would be quicker. But it gives me this:
These are not closed, and I couldn’t find a way to make them closed. So therefore my question - why are the results of Trim and SDiff so different?
