Select Hole icon Select Holes

The Select Holes tool selects all elements along the selected open vertex or edge. A hole is like a removed face. This tool is a useful shortcut for selecting all the edges around a missing face.

If you have no elements selected, this tool automatically selects all holes in the selected object.

Start with one edge selected, grow selection around hole

This tool also tells you how many holes exist in the Mesh. It is only available in the vertex and edge modes.

Tip: You can also access this tool from the ProBuilder menu (Tools > ProBuilder > Selection > Select Hole).
