Using non-standard threads in NX10

[Nick Green]

I'm sure that this must have been covered before but my searching isn't being helpful so:

I am trying to create a tapped hole with the thread M100x4 unfortunately the hole feature only gives the option for M100x6 and I can't find a way to change this. On the same sort of line, how would I put in a tapped hole to a different thread standard, eg BSP, NPT, UNF, etc.?
The tapped hole feature seems incredibly limited, though this may of course be how the system has been set up.

You should be able to find in Metric-Fine or GB Table

For some reason the standard under Threaded Hole in Customer Defaults had been set to 'Metric Coarse'. Changing this to ISO suddenly revealed a whole load of other thread forms.

However it doesn't address the fact that I wish to have a thread that is M100x4, not M100x6 that is coarse and M100x2 which is the only Metric Fine option. It isn't unknown to specify an OD & Pitch for large diameter threads but it would appear that NX won't let you do this. It also doesn't list all the metric fine threads, e.g. M10x1.0 which I have used a number of times.

Well that has sorted out one issue but raises more questions.
I never heard of any of the GB193 standard, or of any of those listed below it. A quick search on NX help & the internet doesn't give any great help except GB193 might be a Chinese standard.
Could anyone help with what all these standards are?

GB is Chinese standard indeed.

You can edit the files "thd_metric.dat" and "nx502_Threaded_Hole_Standard.xml" to add new dimensions.
