==Description==
: The "brep" command is a command for debugging the NURBS (BREP) functionality in BRL-CAD. It can output info information for a specific object, plot its surfaces, faces, etc., and test the implicit to NURBS conversion and surface-surface intersection functionality.

==Example(s)==
: '''mged&gt;''' brep obj.brep info F 0
:: Output information for the 0th face of obj.brep.
: '''mged&gt;''' brep obj.brep plot S 0-2
:: Plot the 0th to 2nd surfaces of obj.brep.
: '''mged&gt;''' brep sph1.brep intersect sph2.brep 0 0
:: Intersect sph1.brep's 0th surface with sph2.brep's 0th surface, with automatically set max_dis.
: '''mged&gt;''' brep obj.s obj.brep
:: Convert implicit primitive obj.s to BREP form named obj.brep.
