+                            Solid modeling is distinguished from other forms of geometric modeling by an emphasis on being physically accurate, fully describing 3D space.

+                          Raytracing is central to BRL-CAD as a means for performing geometric analysis and for rendering images for visualization purposes.

+                                        BRL-CAD supports geometry in boundary representation NURBS format but also supports robust solid ray-tracing of NURBS geometry.

+                                BRL-CAD can run series of commands piped in or redirected to it via standard input, instead of re-invoking BRL-CAD for each command.

+                                BRL-CAD's hardware support includes everything from minimal laptops and desktops to gigantic distributed supercomputers. And it can be executed on most desktop operating systems.

+                                    While now a fully hybrid modeling system, BRL-CAD has its roots in CSG modeling with implicit primitives.
