SYNOPSIS

brep {obj}info [C2|C3|E|F|L|SB|T|TB|V] [arguments]

If obj is not a brep object, then brep will quit and report that fact. Otherwise, it prints a textual description of the requested information. With not arguments supplied, a summary of data present in the brep object is printed. Otherwise, more detailed information about specified components will be reported.

Return information for one or more 2D parametric space geometric curves.

Return information for one or more 3D geometric curves.

Return information for one or more topological 3D edges.

Return information for one or more topological faces.

Return information for one or more 2D parametric space topological trimming loops.

Return information for one or more surfaces.

Return information for one or more piecewise Bezier surfaces.

Return information for one or more 2D parametric space topological trims.

Return information for one or more 2D piecewise Bezier trims.

Return information for one or more 3D vertices.
