I am trying to use the library to implement IEEE 1785.2a flange. UNC-2B do not appear in the thrads table. Is it possible to add? image

threadlib already has UNC. 2B is the so-called class of the thread and specifies tolerance/allowance. threadlib does not distinguish classes as I considered this overkill for CAD-models that are usually intended for 3D-printing. You are lucky, though: threadlib threads were designed based on class 2 specs, therefore internal threads are 2B (external threads are 2A).
