Use model.mesh(<tag>).feature(<ftag>).create(<ftag1>,"EdgeMap") to define an edge mapping for CopyFace or CopyDomain feature <ftag>.
Table 4-34: Available Properties Use the EdgeMap feature if you need to control how the source and destination faces/domains are matched in a copy face or a copy domain mesh operation. When this feature is present, the source mesh is transformed so that srcedge is mapped onto dstedge. The relative orientation of the edges is specified by the direction property.
