Edge Selection Tool
Use the edge selection tool when selecting edges for the hole filling tool to minimise the number of edges that need to be selected manually.
On the Tools tab, in the Selection group, click the Selection tools icon. From the drop-down list select the Select edge tool icon.
When this tool is activated, the smallest loop containing the already selected laminar and / or
free edges (wires) edges is selected. A laminar edge is an edge that is associated with a single
face.
Note: An edge is laminar when the edge is only on the boundary of a single
face.
Tip: Press Q+C to select the smallest
loop containing the edges.
