The test script below is part of a bigger project. I am trying to rotate a group of objects relative to the world Top view, then shear them over -45° relative to the Right view - using Python/RhinoCommon (WIP).
If you run the script with the first file - “StraightPosts”, it works fine The file is exclusively boxes. If you run it on the second file “StraightPosts2” - which are the same boxes but have some round rods that run through them so they have holes, it fails - on the shear step.
Does anyone know why the shear transformation fails in this case?
