I've been looking at Apex since I started doing inspections. I figured I wanted to be on the same page as a lot of others who have to do diagrams. Well, my diagram needs are numbered because only the exterior inspections require them at this time (as far as submitting them with my reports). I still have to rough something out on site so I can submit square footage. Anyhoo . . . I was wondering what others use. I've tried Google's SketchUp, and it was ok (and free) at best. But, it seemed to have issues with Vista (at least when I first tried it on my new computer). So, what, if, are you using? Kirk
