You can quickly select full or partial component loops and rings with the Modeling Toolkit.
To select an edge loop
. All of the edges in the loop are selected.
To select a vertex loop
.
+ double-click an adjacent vertex along the same path. All of the vertices in the loop are selected.
To select a face loop
.
+ double-click an adjacent face along the same path. All of the faces in the loop are selected.
To select an edge ring
+ double-click a parallel edge along the same ring path. All the edges in the path are selected.
To select a partial loop or ring
+ double-click another component along the same loop or ring path. All the components between the two components are selected.
To subtract from a loop selection
-click or
-click one component along the loop path.
-double click another component along the same loop path. The partial loop is subtracted from the full loop.
-click a component to subtract it from your loop/ring selection.
