That will fail when, instead of turning the rectangle into a pentagon, you rotate it 45 degrees into a rotated rectangle. I suspect that SolidWorks solves this

That will fail when, instead of turning the rectangle into a pentagon, you rotate it 45 degrees into a rotated rectangle. I suspect that SolidWorks solves this by naming each face after, for example, the sketch line segment or arc that it was extruded from. But I'm not sure.
