Firstly we need boundary curves.  These can be obtained by running build topology (Geometry > Repair Geometry > Build Diagnostic Topology) on the entire model (Method = All parts), alternatively you can run build topology on just the surface you wish to convert by setting Method = Selection.   2.  Go to Geometry > Create \/ Modify surface > Merge\/Reapproximate surfaces and choose Method = Reapproximate selected surfaces.  Choose the facetted surface and define an appropriate tolerance (default = 0.1).
