Hi Matt, thanks for sending the model through e-mail. This was a good opportunity for me to give a tutorial on low-level object repair and reconstruction techniques.

Let me know if you get stuck on any spot - I think the most complex area is that the hole on the slanted face is a lot bigger than it seems because it includes the spot underneath the panel. That's the part that is different in this case than in the previous simple architectural window sample.

Someday maybe I can make the untrimmer smarter so that it could work without needing the entire boundary for the hole selected, but it is fairly difficult work to do that so it will be a whlie.
