Create an AcBrBrep object, and initialize it with the set() function, using an AcDbFullSubentPath that was previously set using kNullSubentId and the owning AutoCAD object ID. Create an AcBrBrepFaceTraverser to gain access to the faces of the entire solid, and initialize with setBrep(). For each position of the traverser's topological adjacency list (using repeated calls to the next() function), getFace() provides an AcBrFace that can be used to access the geometry. Other traversers provide access to hierarchically lower topological objects and their associated geometry.
