I’ve got a Mass object with 7 surfaces. I extracted the ones with a XYZ surface. The sloped surfaces are the ones that are left. My idea was to make a filter with all the surfaces crossreferenced against the XYZ-list. I want to isolate the sloped surface.
Use the surface normals (magnitude 1) and length of CrossProduct of the Z Axis. 0 = vertical, 1 = horizontal
See 3Blue1Brown linear algebra series
@Mike.Buttery Thanks a lot! I think i’am almost there. The List.AllFalse is giving me the outcome I wanted. Unfortunately List.FilterByBoolMask doesn’t translate this into the surface of “true”.
It’s a bit hard to diagnose as I can’t see the full graph or the geometry. Pin the info from Vector.Length which would also assist
I forgot to set List.FilterByBoolMask to use Levels (list @L2). Thx
