<documentation>There is precisely one positively directed and one negatively directed node in the boundary of every edge. The negatively and positively directed nodes correspond to the start and end nodes respectively. The optional coboundary of an edge is a circular sequence of directed faces which are incident on this edge in document order. Faces which use a particular boundary edge in its positive orientation appear with positive orientation on the coboundary of the same edge. In the 2D case, the orientation of the face on the left of the edge is "+"; the orientation of the face on the right on its right is "-". An edge may optionally be realised by a 1-dimensional (curve) geometric primitive.</documentation>

<documentation>. The topological boundary of a face consists of a set of directed edges. Note that all edges associated with a Face, including dangling and interior edges, appear in the boundary. Dangling and interior edges are each referenced by pairs of directedEdges with opposing orientations. The optional coboundary of a face is a pair of directed solids which are bounded by this face. If present, there is precisely one positively directed and one negatively directed solid in the coboundary of every face. The positively directed solid corresponds to the solid which lies in the direction of the positively directed normal to the face in any geometric realisation. A face may optionally be realised by a 2-dimensional (surface) geometric primitive.</documentation>

<documentation>The TopoVolume type and element represent a homogeneous topological expression, a set of directed TopoSolids, which if realised are isomorphic to a geometric solid primitive. The intended use of TopoVolume is to appear within a 3D solid feature instance to express the structural and geometric relationships of this solid to other features via the shared TopoSolid definitions. . Note the orientation assigned to the directedSolid has no meaning in three dimensions. It is preserved for symmetry with the preceding types and elements.</documentation>
