It is used to quickly determine the center of the face.

In Autocad you can do the same thing with the MTP or M2P command modifier (or by accessing the Shift Hold right click O snap menu),

when in the middle of another command, like MOVE.

In Autocad of late, the last 2 or 3 years, there are 3D Snaps, and my favorite of those is

the CENTER OF FACE snap, as I have never really had any problem using the 2D snaps

when working in 3D.


I would be quite surprised if Inventor doesn't offer the Center of Face option, in one way or another.
