I’m trying to add “material” to the interior of a profile curve to the point where the entire profile is “filled up with material”. The idea is to use SolidDifference to produce a box beam-like volume with a variable wall thickness, from an “open” edge with a very thin wall thickness to a “closed” edge that is essentially a filled plane.
However, when offsetting a 3000x3000mm rectangle by 1500mm, I get not a “dimensionless point” but an odd(?) profile curve (in red).
The attached file shows offsets of 500, 1499, and 1500mm, respectively. As you can (almost) see, the 1499 offset works as expected, producing a tiny rectangle that I can use for my loft. But the 1500mm offset can’t be lofted.
Is this expected behaviour?
