Hi Anis - the data that is stored in an .lwo or .obj file is polygon mesh data - it is different than the NURBS surface data that MoI is set up to work on.

You can export .lwo or .obj files out from MoI - MoI will calculate a polygon mesh by dicing up the NURBS surfaces into planar facets.

But you can't easily go the other direction.

In general once you are working with polygons you will be using a different set of tools that are focused on working with that kind of data instead.

So MoI can generate that kind of data from its NURBS surfaces, but once you have that data MoI is not the right tool for working on the polygon data further. You need to use a polygon modeling program for that instead of MoI.
