I am modeling a simplified version of the Graf Zeppelin, and I’m having trouble with the gondola. I want the windows to basically look like this, with a perfectly smooth front and square windows:
But I am having trouble controlling the subsurf modifier. If I simply leave everything subsurfed and take out square window holes, they come out circular. If I crease the edges, I get weird effects around the window area. This is the best I’ve been able to come up with, but I still don’t like how flat the window frames look and the fact that there are creases around them.
