Hi Brad,
> I have an FBX nurb model and I need to convert it to a high quality quad poly model.
MoI can generate a high quality
N-gon model, which is not the same thing as an "all quad" model. The meshes that MoI generates will be quads in untrimmed areas of surfaces, but there will be n-gons formed at trimming boundaries where any trimming curves slice away regions of the surface.
There isn't any way that I know of to directly convert a NURBS model into an all-quad polygon model, you would usually need to look at a retopologizing step in order to do that. Check out either 3D Coat, ZBrush, or Topo Gun for retopology tools.

You've probably read some incorrect information that was confusing an N-gon model with an "all quad" model.
An n-gon model will produce things like one single polygon for the top cap of a surface like this:
That gets one single big n-gon for the whole top cap. But it's not a quad, it's a many sided polygon. This kind of meshing generally produces the most lightweight poly structure possible with the fewest number of edges in it. An "all quad" mesh for a case like this would be considerably different, it would involve tiling the top face with a whole bunch of quads that tried to follow the general shape of the trimming boundaries.
Some of those retopology tools can help you to construct that kind of output.

It's done by using retopology tools.

That means that the 3DM file probably contains either only polygon mesh geometry or blocks in it rather than regular NURBS objects in it. MoI only reads regular NURBS objects out of 3DM files.
