Hi xrok1 - unfortunately there are a couple of difficulties that get in the way.

One big one is that MoI and Sketchup use very different methods to represent objects - Sketchup uses polygons and MoI uses NURBS surfaces. This makes it difficult to do bi-directional data transfer.

Also, as far as I am aware Sketchup has not made public the specifications for how their .skp files are structured which also makes it a lot more difficult to try to read and write to their file format.
