Hi people, I'm new here and I'm having some trouble at my workplace. I use AutoCAD 2016 but my boss uses R14 (no, she doesn't want to update, not at all) and she can't open some of my files. It's some kind of random error and I can't identify any posible reason for it. When she tries to open it, it shows a blank model space and her AutoCAD freezes up completely in the "regenerating model" stage, not being able to close it anyway but with the task manager. Is there any solution for this? It's driving me crazy, I feel like that episode from The Simpsons where Mr. Burns asks Don Mattingly to shave his sideburns (you can guess who is who here)
