“””””” I did some tests but the 3dm files saved with Moi3D surfaces are not imported while those saved with RhinoV5 are imported correctly,and wonder why?”””””
Rhino uses a concept of saving the “display render mesh”
They arent using NURBS. It is basically a polygon model
MoI does not save this mesh data in a 3dm.
You should be able to get the same results if you do a “save small” in rhino. This drops out the render mesh to save on file sizes.

I thought and assumed that the add-on also makes on fly the tessellation.

Some more details on what Burr mentions here:

Often times 3DM import plugins like this kind of take a shortcut and don't do any tessellation of their own. Instead they rely on a cached tessellation being present in the file. MoI doesn't write that because it significantly bloats up file size.
