It seems like it’s been almost half a year since I wrote TFME4: Tools of the Trade in which I explored the serious options for 3D CAD on GNU/Linux, and didn’t think we had much. I advocated building something on top of Blender, which may still be a decent idea.

But I’m starting to think I gave really short shrift to the US Army Research Lab’s BRL-CAD, which has recently released a new version (7.8.0) with support for Windows and a number of user interface and modeling tool improvements.
