The properties of cosmetic threads include: You can represent threads on a part, assembly, or drawing, and you can attach a thread callout note in drawings. This will allow you to position the thread note to the dimension. Its more common if the fastener is special, such as made for use in aircraft. The conical taper symbol is placed with a dimension value to indicate that the value is controlled as a standard taper. Tims question is as follows: We tend to use true position on threaded holes. What is Straightness (GD&T)? 2. use show dim to place the GTOL outside of the drawing border to have easy access to modify it. To help decipher the number ratings, look up a conversion chart online. If you change a hole dimension in the model, the callout updates automatically.

There is something called an "entity" in the reference type when placing a control frame, pick the type of G_TOL that you want, the ref type changes depending on which control tolerance you pick, then see if you can attach it to a call-out using one of the references that it gives you, maybe entity will work, if its available. . LUO: Laboratory Use Only. This callout sets a standard on how straight a feature must be along its length. Jbeckhou -- I don't know if it's been mentioned above as to what standard your drawings are using (and there should indeed be a note imposing a standard) but the ASME standard Y14.5 clearly states in paragraph 1.4(e) that "the drawing should define a part without specifying manufacturing methods.".
