Shrink Selection

The Shrink Selection action removes the elements on the perimeter of the current selection. It performs the opposite action of the Grow Selection action.

In this example:

• Left image: Five faces are selected.
• Right image: The Shrink Selection reduces the selection down to just the central square.

This action is available in the vertex, edge, and face modes.

Tip: You can also use this action with the Alt/Opt+Shift+G shortcut, or from the ProBuilder menu (Tools > ProBuilder > Selection > Shrink Selection).
