BRL-CAD 7.26.0
Open-source CSG solid modeling and analysisBRL-CAD is a free, open-source solid modeling system built around constructive solid geometry. Its interactive editor creates models from primitives, surfaces, and meshes, then combines them with Boolean operations. Parallel ray tracing supports rendering and geometric analysis, while path tracing produces realistic images. The package also includes image and signal-processing tools, a benchmark suite, and libraries for geometric representation.

BRL-CAD for Windows 10 - Full description
BRL-CAD is a computer-aided design system for creating and analyzing solid models with constructive solid geometry (CSG). It is suited to engineers, researchers, educators, and technical teams who need to build detailed three-dimensional models and examine their physical geometry. Developed at the U.S. Army Research Laboratory, the package combines modeling tools with rendering, analysis, and image-processing utilities, and has applications in military, academic, and industrial work.
The interactive geometry editor lets users create objects from CSG primitives such as boxes, ellipsoids, cones, and tori, as well as from surfaces and mesh geometry. Objects can be combined with Boolean union, intersection, and difference operations to form more complex shapes. This approach supports workflows where a model is assembled from recognizable solids and refined through explicit geometric operations. BRL-CAD also handles NURBS and B-spline surfaces, n-Manifold Geometry, and faceted meshes, giving projects more than one way to represent a part or structure.
For visualization and technical evaluation, BRL-CAD includes parallel ray tracing for rendering and geometric analysis, along with path tracing for realistic image synthesis. Network-distributed framebuffer support can be used in rendering workflows, while image- and signal-processing tools provide additional ways to work with visual and numerical data. A system performance benchmark suite is included for measuring computing performance. The package is a collection of more than 400 tools, utilities, and applications, supported by libraries for geometric representation.
The software has been used to model vehicles, mechanical components, weapons systems, and architecture, and to support vulnerability and lethality analysis. Other reported application areas include radiation dose planning, medical visualization, computer graphics education, and teaching CSG concepts. Its broad toolset can serve both production modeling and technical study, though users may need to select and learn the tools appropriate to a particular task.
BRL-CAD is free, open-source software distributed in source code and binary forms. It is developed for multiple operating systems, including Windows, Linux, and macOS; Windows 10 is among the supported environments. The package has a long history of cross-platform development, and its many separate utilities and libraries make it a substantial system rather than a single-purpose modeling application.
