BRL-CAD is an Open Source, Cross Platform 3d CAD modelling software with more than 20 years of active development.

Few reasons to choose BRL-CAD

Free & Open

You have full right to know what's inside and freedom to customize.

BRL-CAD respects your freedom so our code is open source under OSI approved license terms, which means you can customize it according to your needs.It also means that you will get this software Free of cost and we won't charge you ever for any update or support.

Powerful

More than 400 tools, utilities, and applications comprising more than a million lines of source code.

BRL-CAD is a combinatorial Constructive Solid Geometry (CSG) solid modeling system that includes interactive 3D solid geometry editing, high-performance ray-tracing support for rendering and geometric analysis, network-distributed framebuffer support, and libraries for robust high-performance geometric representation and analysis and much more.

Since 1979

Proudly one of the oldest Open Source repositories in the world.

Mike Muuss began the initial architecture and design of BRL-CAD back in 1979. Development as a unified package began in 1983. The first public release was made in 1984. BRL-CAD became an open source project on 21 December 2004.

Trusted by U.S Military

Solid modeling for strong defense.

BRL-CAD is choice of U.S Military. For more than 20 years, BRL-CAD has been the primary tri-service solid modeling CAD system used by the U.S. military to model weapons systems for vulnerability and lethality analyses.
