1. A method comprising: supporting a test object having a pair of opposing test surfaces that are longitudinally aligned by cantilever portions of the test object to spatially separate the test surfaces forming a gap therebetween; zeroing to a reference datum along an axial direction coextensive with a plane that includes a longitudinal axis of each test surface; and determining both an axial spacing in relation to the reference datum and a static attitude of each test surface by encroaching the gap with a measurement device without altering the longitudinal alignment of the test surfaces.
