There are more than 200,000 measured downloads of BRL-CAD a year and more than 10x that visit our website. About 25% of those were for non-Windows downloads. Approximately 9% of that total were specifically for Linux binaries. Again, those are just our measurable counts not accounting for installs from portage, apt, or source tarballs, etc. I'd say the demand is certainly there, at least for free (as in beer) CAD software that is feature-filled and easy to use. Most open source CAD does great on the free part of course, but fails new users on the latter two, BRL-CAD included. That's why one of our biggest efforts has been on (vastly) improving usability via a new GUI and hybrid representation support. We have a fantastic set of libraries and a huge wealth of features, but our command-centric GUI has a very steep learning curve that is particularly hard on new users. Others are often looking for features that aren't correlated well with the solid modeling domain we focus on (e.g., 2D drafting features). Now the demand for *commercial* CAD on Linux is another matter altogether, but then that's not something that personally interests me very much. I firmly believe that open source CAD is where we (as a community) should be investing effort, evolving our own future. Cheers! Sean
