TUDX, TUDY, TUTX, TUTY, TUTZ: Tolerance on User Defined Tilts & Decenters

These five tolerances, TUDX, TUDY, TUTX, TUTY, and TUTZ, are used for more general user defined tilts and decenters. The names are mnemonics for Tolerance User Decenter/Tilt X, Y, and Z. These are very similar to the TEDX, TEDY, TETX, and TETY tolerances. The difference is that OpticStudio does not automatically insert the required coordinate break surfaces to achieve the specified decenters and tilts in the tolerances. To use the TUDX, TUDY, TUTX, TUTY, and TUTZ commands, you must have already defined the surface specified by Int1 to be a coordinate break surface. Normally, but not always, there will be a second coordinate break later in the Lens Data Editor that has a pickup solve on the toleranced parameter. The pickup solve may be positive or negative, as the case warrants. This permits some complex pivoting and decentering about arbitrary points, with a certain finesse required. Min and max are in lens units for TUDX and TUDY, and in degrees for TUTX, TUTY, and TUTZ, just like the coordinate break surface.
