Hi Andras - do you mean you were expecting a 100% completely identical surface with every single surface control point in the same spots?

There are some things where that will happen like with Extrude or Revolve where the surface construction technique is simple and follows a very standardized pattern, but there will also be several cases where that won't happen.

Certain surfacing commands involve a "refitting" step where new curves are created that follow along the other curves but are reconstructions of them.

That fitting process is not a kind of simple process that is always the same between every fitting algorithm unlike Extrude or Revolve for example.

Network in particular involves a refitting process on every curve.

There are also other differences between some of the other parts of the algorithms, like for example Rhino's Network command kind of pretends that sharp corners in the curves do not exist and kind of sags away from the corners, while MoI's pays attention to sharp corners, stuff like that. For an example of this see the attached NetworkSharpCorners.3dm and zoom in to the corner after you create a Network from these curves in Rhino.

> So, no mix?!

Why do you say this? You can still mix together the results. After things have been calculated they are just all surfaces and you can move the surfaces back and forth between the programs.
