Edge Ports
Edge ports can be applied to an edge defining the boundary between two sets of faces.
Faces referenced in the port definition must belong to the same part for a valid port definition.
Note: An edge port can be applied to a single UTD
face, but the faces on the other side of the defined port must be standard MoM faces.
