1. A calibration rig comprising:
a plurality of vertical calibration legs;
a plurality of horizontal calibration legs;
a plurality of calibration joint locators, wherein each of the calibration joint locators includes a first groove that intersects a second groove at a 90 degree angle, the first and the second grooves each sized to receive at least one of the plurality of the vertical legs and/or at least one of the plurality of horizontal legs in an assembled state, wherein each of the calibration joint locators defines a center hole positioned at an intersection of the first and second grooves, wherein the center hole extends through the calibration joint locator; and
a plurality of control point inserts, each of the control point inserts has a bottom surface that attaches to a work surface, wherein the control point inserts are sized to fit within the center holes of the calibration joint locators in the assembled state, further wherein the calibration joint locators, the plurality of vertical legs, and the plurality of horizontal legs are removed from the control point inserts in a disassembled state, so that the control point inserts function as a benchmark for construction.
