What you can do is set-up Customer Defaults the way you want your colors and whatever and then after Exiting and resarting NX, create one of those new 'Blank' parts. Now if you don't already have a user defined tab on your Resource Bar, just select any tab and when it opens place your cursor over some 'white space', press MB3 and select the 'New Palette' option. Now open this new tab and again, place your cursor over some 'white space', press MB3 and select...
New Entry -> Visualization Template
...and when the dialog comes up, give it some useful name and hit OK.
Now when you need to update the visualization settings on an existing Drawing, simply open the Drawing, go to that tab and DRAG the icon you see there (that was created when you defined the Visualization Template). When you do that, all of the various visualization settings, such as the color settings, which CDF file to use, as well as other settings like background colors, defaults lights, selection options, grids, etc., that you set in Customer Defaults will be applied automatically to your Drawing. Now just save your file and it will be updated to your latest visualization settings.
