Hi Michael,

Thanks very much for the hint! I'll try it out. From what I can see, the resulting shape will be slightly different when applying this solution. Nevertheless, I'll give it a try and report if it can be applied for my use case.

best regards

Hi!

It turned out that the triangular prisms integrated in my model are not causing visible creases (lucky me).

Nevertheless, thanks again for the hints - I'm having the feeling that this knowledge is needed, sooner or later :-)

best regards

Bernhard



P.S.: it took me a while to figure out how to create a triangular prism that has control points: you need to loft two adjacent lines and then extrude the surface. When instead extruding a plane polygon triangle or lofting two polygon triangles (with closed caps), then you loose the control points (because the control points of the individual surfaces don't align).

Interesting info, thanks PaQ and Michael. I didn't know yet that combining SubdivClassic with the regular Subdiv has its advantages.
