When marking a hole, for instance, you can set the combination square to the X and Y distances to the hole from the edges of the workpiece, and scribe two lines to establish the point (use the blue marker to provide some contrast before scribing). Then mark the hole with a center punch, and drill with a center drill before the actual size you want, as twist drills tend to walk.

Our team uses this for most everything we cut that isnt on the vertical mill or the lathe.
