Hi Tom, in this case it's not really about standards, it's about different kinds of base technology.
There isn't just one mechanism to represent 3D objects - there are different mechanisms that can be used to make a 3D shape. Modo and other polygon-based programs use one method (polygon mesh), and MoI and many other CAD programs use a completely different method (NURBS).
These aren't just different ways of packaging the same data, the actual data itself is different between these methods.

My guess would be that the Modo torus is just using more polygons than MoI. This creates a smoother shape at the expense of additional data.
You can adjust the density of MoI's export by using the slider that appears when you save to a mesh format like LWO. If you move the slider a little more towards the right (towards the "More polygons" label), MoI will create a denser output which will then look smoother in Modo.
Generally the focus of MoI is that you would create industrial type models inside of MoI and then you can export those to your polygon program by LWO or OBJ formats.
If you need to import and edit polygon mesh type data, then MoI just is not designed for that type of work, you'll need to use a different program for that type of stuff. It's just outside of the type of work that MoI is focused on doing.
