You may tolerance the wedge on a lens by creating a Boolean Native Object from the addition of two Standard Lenses with the intersection of a Cylinder Volume:











The parent objects may be ignored and hidden be selecting the corresponding parent object rows in NSCE, right-clicking the mouse and selecting 'Ignore and Hide Object':











You can then tolerance the wedge angle by using the TNPS operand:




Note: the Data field above should be set to 4 to tolerance the X-Tilt, i.e. the wedge of the lens.




TNPS defines tolerances on Non-sequential Component (NSC) data. Three integer parameters are required: the NSC surface number (use 1 if the program mode is NSC), the object number, and a code. The code is 1, 2, or 3 for the object’s X, Y, or Z position, respectively; the code is 4, 5, or 6 for the X-Tilt, Y-Tilt, or Z-Tilt, respectively.
