I'm currently the lead maintainer of Solvespace (CAD): https://solvespace.com/index.pl https://solvespace.com/index.pl It's a very fun to use CAD program, but is somewhat limited in capability. When I came across it I loved it but quickly ran into its limitations, so I joined the effort. Long term I don't see it growing into full-fledged CAD, but I'm happy to see it progress and help it along. Some day, someone might undertake the major refactoring of the internals to enable it to go beyond, but in some sense I don't really care. It's just a fun project to work on and I like to watch it grow.
