BRL-CAD has a very rich and ongoing development history that is not immediately obvious. [1,2] Heavily actively used by gov'ts as it has unique features like validated full shotline solid ray tracing -- granted, not a feature most know, understand, or care about but absolutely critical to others. Development is actively funded annually (just not your priorities).

In total, BRL-CAD today has more than 500 full-time staff-years of effort invested, more than pretty much all other open source CAD combined.

There's simply no PR team, and limited bandwidth to provide support to those that don't contribute in kind. CAD modelers coming out of school are only accustomed to multibillion dollar company products that dedicated highly experienced devs to specific user-facing features under dedicated funding lines.

With open source, skillsets vary wildly and coordination, collaboration, and maintenance are a challenge until a project achieves critical mass. It's something the BRL-CAD community is working hard on, but it's not something that will be quick. Contributors are welcome!

Thanks for the info. I didn't want to rain on your parade but it just doesn't seem very active judging from the homepage. Also, if you want more community involvement you should probably provide binaries for platforms like Mac OS and Windows to attract more end users that may eventually lead to more developer engagement.
