Hi Nicola, yes that is something that I do want to add.

I have actually recently sent them a request to get some more information about their file format, but I have not heard back yet so I'm still not quite sure yet how much work will be involved.

Another complication is that I'm not sure if SketchUp will deal with non-planar n-gons very well or not, that may be an issue that it will only like to take n-gons only from fully planar objects.

So I don't quite know all the details on what will be involved just yet.
