Pending the version of NX you're using and assuming you're meaning a blank view that doesn't already exist....
Once the curves are created, you could place a Drawing View (Insert -> View -> Drawing) then copy all of the curves created by the GRIP program. Next, right click on the newly created Drawing View and select Paste from the pulldown. Dimensions, Notes with Leaders and any hatching will not copy over (the hatching might, but it will probably lose associativity). If you delete the Leaders from the Notes, they should copy into the view.
