Abstract
A device and a system for ascertaining dimensions includes at least one gaging block held by negative pressure to a workpiece. The gaging block has a body with a first face and a second face. The first face includes a recess portion therein and the second face defines a measurement reference surface. The body includes a port in communication with the recess portion and adapted for communication with a negative pressure generating device such as a vacuum pump. The gaging block is held by negative pressure in intimate and highly accurate contact with a workpiece in order to provide a reference point for measurements that might for a variety of reasons be most difficult to obtain.
