A computer-implemented solid modeling system performs an operation for
embossing or engraving at least one profile onto or into a solid body.
Generally, the profile comprises text or a planar geometric shape.
Specifically, the profile is a planar face bounded by edges, or the
profile is a set of planar faces sharing a common plane and having the
same normal direction. In performing the operation, the profiles raise or
lower regions of faces with respect to an underlying surface.
