how to add a dimension to a thread..
(OP)
Hi Guys,
how to I add a dimension callout to a thread I have created in drafting space? Is the best way to do it via 'feature parameters' - can I change the way this annotation looks?
many thanks,

If the threaded-hole was added as a feature of your model, then the 'Feature Parameters' approach in Drafting is the way to go.

RE: how to add a dimension to a thread..
sorry yes, that is what I meant. I have created a thread as a feature of my model. I want to dimension that thread in the drafting space - how do I do it?
Additionally if the thread is an internal thread what diameter should I give the starting hole? - the minor diameter as per the chosen thread specifications? and does this matter...
many thanks,
James

NOTE: The tap drill diameter is based on a theoretical value to the closest drill size. This may NOT be what your shop uses as the tap drill size. Edit the thread hole files to your shop's requirements.

Insert -> Dimension -> Feature Parameters...
...and then expand the part file list until you find the desired features. Select them and then select the view you wish to see the dimension(s) created in and then hit OK.

ok, many thanks, got that. One more related question - When applying the thread function as per information from the thread hole files I get the message 'cylindrical face diameter is in conflict with thread definition'. The thread applies ok but I am wondering why I get the message and what it means..
many thanks

I am adding a symbolic thread to an existing hole...
thanks,

BTW, this only applies to Symbolic Threads. If you wish to create a Detailed Thread using the existing function, that will still work with the new Hole features since this will replace the existing hole with a completely new set of faces (the threads themselves) so there was no need to even attempt to update the hole diameter.

RE: how to add a dimension to a thread..
many thanks for the info. So what would be the preferred way to create an internal threaded hole? - create the hole with the hole feature and then add the symbolic thread feature to that hole...?
If adding a symbolic thread to an existing hole created a different way (not via the hole feature) it is safe to ignore the face diameter conflict..?
cheers,

RE: how to add a dimension to a thread..
Now if you're talking about something other than a threaded-hole, such as a bored pocket with a internal thread, while it's possible that you could still make this using a 'threaded-hole' feature, it might make more sense to simply model the as-rough-bored opening and then add a symbolic thread feature. It was exactly for situations like this, as well as external (male) threads, that we kept the existing function in NX since there are some things which just don't qualify as a 'threaded-hole'.
As for what to do about the warning message, all it's telling you is that NX was not able to update the pilot drill size, which means that if it's important that the pilot drill size be precise, you will be responsible for editing the hole diameter yourself since you cannot depend on the Symbolic Thread operation doing it for you. If the diameter is not critical, than just leave it as is as long as it looks OK.
