How to do this actions? Help me?
You need to create setup assembly templates, add them to the setup library, and then create your own pax file that is merged with the system one to display the file new dialog that you show.
The attached presentation is a little old, but you will get the idea.
A note to customers - the image is from our internal and partner demo environment, which is not distributed to customers as part of NX CAM.
See the slides numbered 30 and 31.
Copy the manufacturing pax file from the install to your location, remove all the OOTB entries, and replace them with yours as shown on #31.
