There are thousands of CAD packages out there and most are proprietary because they do proprietary stuff for a niche market.
All the open source CAD packages are general purpose cad (i.e. Basically "drawing") software.
I make a package with 100 man years of dev time that might have a total global market of 2000 users. It's not exactly something that would reach critical mass on github.
Even if we based our software on one of the open source packages we'd still be a huge chunk of proprietary software written as an extension.

CAD isn't just drawing lines.
