Subdivide Face icon Subdivide Face

The Subdivide Face action splits each selected face. To do this, it adds a vertex at the center of each edge and connects them in the center.

Tip: You can also use this action with the Alt/Opt+S shortcut, or from the ProBuilder menu (Tools > ProBuilder > Geometry > Smart Subdivide).
