What is the best way to create a collar in a case like this?
I think about two ways of making this collar:
a) perpendicular to neighbour side walls (or with other specific angle different than 90 degrees);
b) parallel to XY plane.
Offset in Top or Perspective view and select the surface edge as the curve to offset. Repeat for each surface.
Loft between the surfaces edges and the offset curves. collar_test_DC01.3dm (1.6 MB)
