OT: can someone help me with an open-source CAD program?

[Pierre Abbat]

I've been working on a surveying CAD program for several years and it's 
nearing the point where I'd like others to hack on it. I need help with the 
file format, import and export, and GUI. It runs on DragonFly (my build system 
is hosed, but I just ran it on leaf) and Linux. If you can help, or know 
someone who can, let me know.
