BRL-CAD is a powerful cross-platform 3D solid modeling computer-aided design (CAD) system

 

BRL-CAD provides geometry editing, ray-tracing, geometric analysis, image and signal-processing, performance analysis tools, networking infrastructure, a high-performance geometry engine, and much more.  It's more than a million lines of code, 400+ binary applications, dozens of libraries, and has been under development for more than 30 years.

 

So it's a graphics system, but not like Blender or 3D Studio Max.  We focus on solid modeling and engineering analysis needs (CAD, CAM, CAE) where users need verifiable scientific accuracy.  If you've heard of them, we're a little more like AutoCAD, Solidworks, Pro/Engineer, or CATIA just without the polish.

 

Help improve open source CAD!  We have tons of tasks that are doable within a couple hours even with practically no experience.  Some are programming (C, C++, Tcl, shell scripting, PHP, ...) while others involve creating diagrams, writing, modeling, or testing.

 
We want you to get excited about open source CAD!  It's hard work, but really fun.  Our goal is to become the best solid modeling system out there, but open source needs people like you to make it your hobby. We're here to help you get started.
