When I have a viewport in ACA 2008 and use 3D orbit to rotate the view to a perspective, no matter what visual style I use, it looks X-ray. It's not the full X-ray mode (that is turned off), but the walls are somewhat transparent and I can see walls and windows that should be hidden. Any ideas?
I think its a setting somewhere. The same drawing was started in ADT 2007, and I was having save and viewport issues. I copied it to an ACA 2008 template, and that's when it started. The new drawing based on the 2008 template does it in 2007 now. On a brighter note, I think the save and viewport issues have been fixed!
