As titled, just set it up as opensource CAD package seems to be real fast under my AMD64 Fedora Core 3 box. Runs on about every OS you can think of, has exports/imports for all the popular formats.

http://sourceforge.net/projects/brlcad/

I have loaded it, and was able to get it started and use it a little on a Linux and a Windows machine (XP Pro), but I am still learning to use CAD so really cann't say much pro or con.

The windows was easy to install, and for Linux, I did a source install on an UBUNTU system (untar the package and read the INSTALL file. ... In the end it is basicaly a standard: configure, make, make test, make install senario, really easy).

Now, I want to generate g-code for my home HobbyCNC setup. From BRL-CAD what would I do to do that? Save as a DXF, then dxf2gcode?

I also would like to generate STL (3d lithograph file), to run on a REPRAP (see reprap.org - basically a homebrew 3d lithography machine). Any idea how to export to STL?

Thanks ... Jack
