Edges are the boundaries of faces. Wires are not associated with faces and are often
referred to as “free edges”.
Selecting an edge or a wire in the 3D view selects the corresponding edge or
wire in the details tree. Conversely, selecting an edge or wire in the details tree selects the corresponding edge or wire in the 3D view.
Figure 1. Select an edge in the 3D view to highlight the corresponding entry in
the details tree. The converse is also true.
The following can be applied to an edge:
Local mesh size
The following can be applied to a wire:
Local wire radius
Wire core medium (metallic, layered dielectric, impedance sheet)
