A command sequence I have used a lot in the past has suddenly started to fail unpredictably. Rhino Version 5 SR14 64-bit (5.14.522.8390, 05/22/17)
I intersect cut planes with a solid polysurface → trim then pipe the resulting curves → split the poly with the pipes → shrink then offset surfaces for new closed polysurfaces. The atttached image shows the result as of today. What is causing this failure?
I have attached the model file. Happy for any assistance.
TIA Robb
