Synopsis

ExpandBySegments()

Details

Description

ExpandBySegments is used as the criterion parameter of OOF.NodeSelection.Expand_Node_Selection. It expands the current Node selection by selecting all Nodes that share a Segment with a Node that is already selected. When a Skeleton contains quadrilateral Elements, ExpandBySegments may select fewer Nodes than its colleague ExpandByElements will.
