Features for Virtual Operations Table 3-11 lists the features that correspond to virtual operations: Table 3-11: Virtual Geometry Related Features (Only 2D and 3d) Name Description IgnoreVertices Virtually remove isolated vertices or vertices adjacent to two edges only IgnoreEdges Virtually remove isolated edges or edges adjacent to precisely two faces or between two domains IgnoreFaces Virtually remove isolated faces or faces between two domains CompositeEdges Form virtual composite edges from sets of connected edges by ignoring the vertices between the edges in each set CompositeFaces Form virtual composite faces from sets of connected faces by ignoring the edges between the faces in each set CompositeDomains Form virtual composite domains from sets of connected domains by ignoring the boundaries between the domains in each set CollapseEdges Virtually collapse each edge into a vertex by merging its adjacent vertices CollapseFaces Virtually collapse faces MergeEdges Virtually merge edges adjacent to face MergeVertices Virtually merge one adjacent vertex of an edge with the other adjacent vertex
