Specify thread major diameter in fractional inches for external UNC UNF threads.

Specify thread major diameter in fractional inches for external UNC UNF threads.

Hello all,


It seems Creo supports the display on a drawing of the major diameter of an interal thread as a fractional value natively, but not for external cosmetic threads as an engineering feature. See attached pdf for brief overview.


In our library I found examples of external threads with fractional major diameters, but they were faked, i.e. it was not a parametric driven directly by the feature creation.


I did a search for this issue here and at ptc communities, and in PTC support. Officially PTC CS155631 says this isn't supported, but I just wanted to see if anyone in the community had any thoughts on this matter.


Anyone have any comment?

I am with PTC on this one. I wish that there was a way to create external
threads and have it show up as a note on the drawing.
