customer wants the thickness of a part at a set of grid points in calypso (i think its ver7)

Its like a 60x20x1mm thick little plate.

pretend you glued graph paper to it and wants the thickness at all the intersections and record them, i have x,y coordinates for the points, but i have no idea how to program for a particular x,y. , ive only ever scanned before, or just chosen a point visually, I can set up the alignment for a rectangle and get 0,0,0 but after that no idea.
