Selects geometry connected to already selected elements. This is often useful when a mesh has disconnected but overlapping parts
If any vertices are selected,¶
All the vertices in the isolated geometry which includes the first select vertices will be selected.¶
If any edges are selected,¶
All the edges in the isolated geometry which includes the first select edges will be selected.¶
If any polygons are selected,¶
All the polygons in the isolated geometry which includes the first select polygons will be selected.¶
