Well, my example was made in C4Pro, so..... But it's a result of carrara's N-gons. Carrara is one of a small # of 3D programs that can have polygons with a virtually infinite # of sides, Biggert's "canopener", for example, has 14 sides. Most other progams won't fill in a polygon with higher than 4, possibly 5, sides. If you're building for export to another program, you'd have to do this anyway(I usually run almost everything through Poser5, even though I bring the poser files back into Carrara for rendering.). Also, if biggert or I had chosen to extrude on a different axis, we'd never have encountered "pac-man syndrome".
