I noticed this in NX5, with the file new dialog has templates to choose from to base your part off of. By default there is a ‘blank’ file which will work as desired, but what if you had a set of english and metric files; Assembly, model, and analysis files. That is a lot of template files to be constantly updating. The interesting thing to note is when you create a new file based on one of these files, the settings that are part specific also go along for the ride. This is good and bad. If your drafting settings for example need to be tweaked, do you really want to change each and every one of these files? I don’t, so I’m glad to see NX has a setting in the customer defaults to override what is in the part.
In the customer defaults:
Drafting -> General -> Drawing -> Drawing settings -> use Settings from standard (option)
