ABSTRACT:
A measurement referencing and transferring technique includes locating a platform base at a working location, mounting a sighting mechanism having a sighting axis on the platform base, and sighting a selected point on a first object in a given direction from the platform base by adjusting the position of the platform base relative to the working location thereby directing the sighting axis of the sighting mechanism toward the first object, and aligning the axis incident with the selected point on the first object. A reference point is then marked on a second object in a direction opposite the given direction from the platform base, by observing along the aligned sighting axis in the direction away from the first object, and defining the reference point as that point on the second object with which the sighting axis is incident. A measurement associated with the selected point on the first object is determined by referring to the reference point marked on the second object.
