I have some drawings an architect did for me that I would like to open in some CAD program and hopefully make some modifications. The catch is the architect did the drawings in Softcad (I believe version 11). My understanding in that this version could not export to dwg. The files he sent me have an spd extension. Anyone know of any way of getting these opened or converted to another format? Any CAD program on Linux be able to open them? Right now I have no specific CAD program running on my Redhat or Fedora machines. A "free" one would be preferable. Being an off topic question replies can be sent to me directly if anyone has any ideas. Thanks, James
