Having had an object refuse to explode and separate out its inner and outer surfaces, I try for a segment of it.
Still the inner and outer main surfaces are bound along the one edge (small filletted edge) after exploding this segment.
I am trying to extract just the outer main surface with holes in and delete all radiused edges etc.
ExtractSrf also refuses to extract just the outer face.
