Presently, we check insulation thickness through color coding.

Has there been any user request to produce geometry that represents insulation and cladding?

It would seem beneficial, especially when the user fails to imagine how insulation impacts u-turns, base support selection, etc.

CAESAR's prepip display doesn't seem like it produces so much geometry that you could overload modern graphics cards, but I guess an option that transforms present geometry to where OD-> OD + thickness*2 and Radius -> Radius - thickness makes sense on heavier models.

But a second model in place with or without transparency would be beneficial on smaller models.
