The $500 "professional" CAD software decided to crap out on me again, this time during a file save and corrupted two weeks worth of work. The file is now "damaged" and won't open. I was nearly half done with the hull texture, but now get to start over. I've said it before, I'll say it again - if you're shopping for professional CAD software, stay away from TurboCAD Mac Pro - it is absolute garbage. Some people (including Apple "engineers") simply are not qualified to be programmers.
