What happened to the Metric Additional Series in Metric Thread sizes?

[NutAce]

Hello All.

With the changes in the thread feature (NX7.5 - 8.5) it is no longer possible to apply them to a general hole type (without manually referring to expressions).
In the thread feature there is the Metric Additional Series available which seems to be removed from the series available for the threaded hole types...

For instance, I would like to apply M52 to a Threaded hole type. GB5796 has a M52x8 available but I would like to apply M52x5 which was available in Additional series...
What is the reason it is removed?

I'm sorry, but there is no such thing as a 'Metric Additional Series' thread standard in NX, and I don't mean just now in NX 8.5, I mean ever. If there is one on your system then someone has supplied you with a modified copy of the 'thd_metric.dat' file. The reason that I'm sure about this is that of all of the pieces and parts of NX that you see today, it turns out I was personally responsible for the content of both the 'thd_metric.dat' and 'thd_english.dat' files, used by the 'Thread' feature. So I know exactly what thread standards were included and the range of sizes covered for each of them, and there was nothing called the 'Metric Additional Series'. Sorry, if this 'standard' were never part of the database used by the older 'Thread' feature, it would not have been included with the newer 'Threaded Hole' feature when it was introduced in NX 5.0.

Thanks John.

Then I will contact our developers to see if they can bring it back...

Hi John.

Any plans on bringing in the additonal ranges (2nd Choice and 3rd Choice) as stated in ISO_261-EN-2010 ? ( See attached exerpt )

That's no longer up to me (I did that 'thread table' work years ago when I was a Product Manager). My advice is to contact GTAC and open an ER (Enhancement Request).

That being said, the so-called 'thread tables', whether we're talking about the older .dat files used by the 'Thread' feature or the .xml files used by the newer 'Threaded Hole' feature, they can both be edited to eitehr remove unwanted (non-standard for say your organization) sizes as well as adding additional sizes or even entire new classes. It's just a matter of getting the specifcations for the threads of interest. Often these can be found in the Machinery's Handbook or you can purchase the specific specification from the various standards organizations auch as ANSI/ASME. This is what I had to do a few years after we first implemented the original 'Thread' feature when we were requested to add the UNJ classes, which were not found in the Machinery's Handbook and so I had to buy the standards document.
