CAD softwares for Linux
Posted on October 4, 2007 by Dude
Cad-Schroeder has recently released a Free personal license of Medusa CAD, free of charge !
I believe the Medusa was originally made for Unix, and therefore are naturally available for Linux.
It handles DWG, DXF formats and have some basic 3D capabilities.
