A checking fixture for checking the accuracy of manufactured parts has a base with origin surfaces or tooling balls defining an orthogonal plane system. A series of net pads, clamps and pins formed on or in the base supports a manufactured part to be checked in a known position relative to the plane system. A plurality of data collection device holders are attached to the base. Each holder has a datum element such as a bushing or the like. The exact positions of the datum elements relative to the plane system are measured and stored in a data storage device. A computer is programmed to accept data from the data collection devices and compensate for variations of the known datum element positions from theoretically perfect positions.
