Abstract
In accordance with the present invention, there is provided an edge adapter for use with a spherically mounted retroreflector device for measuring the location of a measurement point on a first object surface of an object. The object has a second object surface with an edge interposed between the first and second object surfaces. The measurement point is positioned an offset distance from the edge. The retroreflector device has a spherical outer surface. The edge adapter is provided with an adapter body having at least two engagement points. The engagement points and the measurement point are cooperatively sized and configured to define a sphere of substantially the same radius as the spherical outer surface. The edge adapter is further provided with an adapter base attached to the adapter body. The adapter base has a base surface formed to engage the first object surface for supporting the edge adapter thereat. The spherical outer surface of the retroreflector device is placed in contact with the engagement points of the adapter body and the measurement point of the first object surface for measuring the location of the measurement point.
