Customer defaults can be exported and imported using Manage Current Settings (Eye icon located at upper right corner of customer defaults window)
Did you mean Drafting Standard? ie you created your own Drafting Standard and you want to make that available to all your users?
if you are in the customer defaults then you can export 2 kind of settings.
in the dialog of the drafting standard you can do a save as.
this will save the drafting standards to your NX user folder located in appdata/local/siemens/NX(version)
If you have the drafting standard file that you created you can import that one in that of the other users.
Or like i mentioned before you can set the UGII_SITE_DIR and save all the company defaults & drafting standars on the site level en then it will always be available for all the users. (if there is also the UGII_SITE_DIR been set)
If you want to share NX settings between users, I suggest you download the "NXCustom" setup (see the "NX Customization & Programming" forum here, in the "NXCustom utilities" thread pinned to the top of the list)
Download the version that corresponds to your NX version, un-compress it, and read the "readme.txt" at the top level.
This shows a pretty complete setup that works in both Native & Teamcenter environments.
Production: NX10.0.3.5 MP16/TC11.2
I'd rather be e-steamed than e-diseaseled
