Shrink Selection

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

Shrink Selection Example

In this example:

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

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

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