Claim 1
Independent Claim
188 words
The method of aligning remote axes parallel to a laser bema which has a normal position which extends perpendicular to a base line through a pair of bench marks and at a determinable height and at a determinable horizontal distance from at least one of said bench marks comprising the steps of: reflecting said laser beam at a first angle and perpendicular to its normal position such that the reflected beam points at one fo said bench marks, reflecting said laser beam at a second angle at right angles to its normal position such that the reflected beam points at the other of said bench marks, determining the height of the normal position of the beam above said base line from said first and second angles and the known distance between said bench marks, determining the horizontal distance between one of said bench marks and the projection of the normal position of the beam on said base line from said height of the normal position of the beam and one of said first and second angles and, aligning remote axes parallel to the laser beams said normal position.
