The short answer is NO, but you can section the faceted body to create curves from which you can possibly rebuild the geometry. Later version of NX Studio Tools contained a function which assists in that process, but it nevertheless requires that you work with curves to extract the geometry.
On the off chance that the faceted body was retrieved from a JT file then you may be able to retrieve the equivalent of a Parasolid, but this only occurs because the data originated in NX. Check out File>Properties>JT File>Extract Exact Data. If you hadn't opened a JT file in the first instance tabs will be absent or greyed out.
There is no way to extract surfaces directly from facet body so far in Shape Studio Application in NX.
you can try following functions if you like,
01 you can use Section Analysis and create section curves, and then mesh surfaces using these curves.
02 you can use Rapid Surfacing to create faces from one facet body.
03 you can also use Refit Face function to refit one face to your facet body.
