I'm currently using AutoCad 2000 / Win XP. I've written my own extensive screen menu, and I've written and download dozens of AutoLisp routines. The screen menu and AutoLisp routines are essential to my productivity. I'd like to upgrade to Win 7 (already have new machine) and AutoCad 2013, but my AutoDesk reseller (U.S. CAD) can't tell me whether or not I'll be able to use my Acad 2000 screen menu and AutoLisp routines with Acad 2013. Anyone out there have any information on this?
