Hi @TomR_au ,
Thank you for the video, it was exactly what we needed to see.
I have reproduced the behavior on my side.
Here is the summary:
- The issue occurs when delete the token %Prefix from the numbering format.
- Basically, the numbering does not allow you to not use the token %Prefix. When the token is not included, AS will still use it; it will use the default format (%Prefix%Counter%MethodNumber), so this is why it looks like it does not save the numbering settings.
Currently I am not very sure this is an "issue", due to possible conflicts that could appear if the token would not be used.
Let's say you do not use the token %Prefix for numbering, but you do have assemblies with prefix (from StandardPartTemplate, as example). What should be the behavior of numbering ? To discard / delete the prefix completely ? To keep the prefix but to not show it ? These situations might lead to confusion or mistakes.
I would suggest to keep the token %Prefix in the numbering method. As long as the prefix is not activated or it is not set manually, it should not affect in any way the numbering result.
Please let me know if it makes sense what I explained.
Best regards,
Emy
