Merge Edges
To virtually merge opposite edges adjacent to a face, on the Geometry toolbar, from the Virtual Operations menu (), select Merge Edges (). Then enter the properties of the operation using the following sections:
Edges to Keep
Select the edges that you want to keep in the Graphics window. They then appear in the Edges to keep list.
Click the Active button to toggle between turning ON and OFF the Edges to keep selections.
Edges to Remove
Select the edges that you want to remove in the Graphics window. They then appear in the Edges to remove list. Click the Active button to toggle between turning ON and OFF the Edges to remove selections.
The operation merges the opposite edges by collapsing the face between the edges and reconnecting the faces adjacent to the removed edges to the resulting merged edges.
