I need to get my dad to try CYCAS and see if his old autocad files will open in CYCAS in Linux.
Compatibility with DXF (and DWG?) has been a hold up for converting his desktop to Linux for years. He is still running a version of Windows 98 that was actually installed in 1998. Its the must cluttered and unstable windows desktop I’ve ever known.
Ubuntu + CYCAS might just be the ticket.
