Summary0004498: Loft between sketches with inner and outer elements created in different order results in bad 3D geometry
DescriptionWhen creating a loft, the order the sketch elements are created should not matter, but it does.

Take the case of lofting between two sketches, with two circles each, for example, to make a kind of cylinder. In one sketch the inside was created first, and in the other sketch the outside was created first, the loft tries to cross over itself resulting in zero thickness geometry and a 'black part'.
