Is anyone in the GrabCAD community currently using open source CAD software?
If not, have you ever tried any free CAD software?
FreeCAD is probably what you want as far as pure CAD goes. Blender 3D or Blender 2.6.3 is a very good tween package.
There is also http://librecad.org/ it's only 2D though. A shop that I work with now uses that instead of AutoCAD.
I use FreeCAD.
Yes, I am using freecad on UBUNTU
I use blender for 3D, and draftsight for 2D. Both are great programs.
i install Linux Mint 16 Cinnamon 3 weeks ago(,because i used XP Pro,to old for Microsoft),and i try to use Freecad..
but from Solidworks,or Autocad job it's not easier..
