I know what you mean. Converting from triangle faces to a smooth surface is not a trivial operation, this is why you are having such a hard time. Incidentally this is why people complain so much about .STL editing in the 3D printing community, because .STL does not contain the required information to reliably modify a surface. An STL file only contains raw triangles, the surface information is gone. In your case it was never there to begin with, since your files are the result of a 3D scan, not of a CAD session.
As I said Fusion 360 can convert from raw triangles to surfaces, but it gives up easily when there are too many triangles. I don't know how many triangles you are talking about. Once the mesh is converted into BReps, it is editable as surfaces and you can easily output them to .STEP.
