Syntax

bool ExpandSelectionByEdgeLoops
(
FGroupTopologySelection & Selection
)

Remarks

Using the edges in the given selection as starting points, add any "edge loops" containing the edges. An edge loop is a sequence of edges that passes through valence-4 corners through the opposite edge, and may not actually form a complete loop if they hit a non-valence-4 corner.

Parameters

Parameter	Description
Selection	Selection to expand.
bool	true if selection was modified (i.e., were the already selected edges part of any edge loops whose member edges were not yet all selected).
