Edge Map
Use an Edge Map node () to specify the orientation of the source mesh on the destination for a Copy Face or a Copy Domain node. Using this node, the source mesh of the Copy Face or Copy Domain operation is transformed so that the source edge of the Edge Map node is mapped onto the destination edge of the Edge Map node with the specified orientation.
Edges
Click the Active button to toggle between turning ON and OFF selections.
Activate the Source edge list and select the edge that you want to define as the source edge in the Graphics window.
Activate the Destination edge list and select the edge that you want to define as the destination edge in the Graphics window.
Orientation
Select Automatic orientation to let the software determine the orientation of the mesh of the source edge on the destination edge (this is the default), select Same orientation to let the mesh of the source edge be copied to the destination edge according to the directions of the edges, or select Opposite orientation to let the mesh of the source edge be copied to the destination edge in the opposite direction.
