An implied face is a closed area that creates a boundary by intersecting or overlapping a face on a 3D solid object.
This variable affects the ability to use implied faces when you press Ctrl+Shift+E and drag the area inside the boundary to create an extrusion dynamically.
This variable must be set to 1 if you want to select and modify implied faces.
