Whipped this up in response to this thread. Pro/E Wildfire 2.0
The good old mobius strip
It looks like it’s actually a Moebius prism. It looks way cool, but it doesn’t have quite the same topological significance.
I knew it was Pro/E at swept blend. Nice job though, I’m trying to adjust to Wildfire 2.0 myself after not having used Pro much since we were on 2001.
