In 2D and 3D it is possible to reduce the number of vertices, edges, faces, and domains of the geometry by using virtual operation features. To add the first virtual operation feature to a sequence you need to build the finalize feature by entering
where <ftag> is the feature’s tag (an identifier of your choice), and
ftype is the feature’s type. To build the feature, enter
The finalized geometry of a sequence that contains virtual operation features is referred to as a virtual geometry. If you form a composite edge, face, or domain by using a
CompositeEdges,
CompositeFaces, or
CompositeDomains feature, respectively (or the analogues
IgnoreVertices,
IgnoreEdges, or
IgnoreFaces features) the resulting edge, face, or domain is referred to as a
virtual composite edge,
virtual composite face, or
virtual composite domain, respectively, or more generally, a
virtual composite entity.
