Solid modeling
Build models from geometric primitives and combine them with union, subtraction, and intersection. Use the interactive MGED editor to construct and edit geometry.
About BRL-CAD
Model solids. Understand geometry.
BRL-CAD is an open-source solid modeling system for creating 3D geometry, analyzing models, and building geometry tools.
Three ways to work with geometry.
Geometric analysis
Inspect ray paths, check for overlaps, and calculate geometric properties with tools such as NIRT and GQA. Choose the analysis and settings that suit your model.
Programmable geometry
Automate geometry tasks with scripts, or use BRL-CAD’s C/C++ libraries in your own applications. Developer guides explain the interfaces and how they fit together.
See it in practice.
Explore procedural models and rendering examples in the gallery, then follow the linked guides to see how they were made. For a deeper introduction to the system and its history, read the technical overview.
Open source. Open to participation.
Read and build the source, ask the community a question, or work through the contributor guide to find a place to help.
