hpdf export format from 3dexperience

Hello all, I'm a long time V5 Catia user and now I'm dealing with a new export format out of 3dexperience.

It comes as an hpdf file which appears to be a zip file format.  Inside that file are multiple files and one is a 3dxml file.

In V5 that file is basically useless because it's just a light render file of a solid with no weight of part history in it. It just looks like it has

many faceted faces that are not real surfaces.   I'm looking for any help on how to deal with this type of file export to get real cad surfaces out of it.
