Looking for freeware or opensource CAD that can read and edit .dwg [closed]
We have an engineer who needs CAD software which can read and edit .dwg files (preferably that runs on Windows but I could probably argue for a *nix box if needed). Before buying a commercial license I'd like to see, what if any, freeware or opensource CAD software exists. I've read through this post but the software here all specifies a license for personal use only. Everything I have found up to this point is a .dwg viewer only, is licensed for non-commercial purposes, or is paid software (with the possible exception of FelixCAD which I'm still looking into).
There are some really cool CAD packages such as BRL-CAD or Archimedes but these don't have the capability to work with .dwg files. My question then is, am I right that there is no freeware (with a commercial license) or opensource CAD software which can work with .dwg files? Or am I wrong and there is just such a package out there?
