Michael,

thanks for all this info,

This note is from the Google site you gave me:

>Before you begin, we have one word of caution. Both the SkpReader and SkpWriter APIs were written prior to SketchUp's >acquisition by Google. Neither API is under active development. However, we do make bug fixes and provide limited support >through the Google SketchUp Developers discussion group.

I've downloaded the files just to see if they where different and it seems they are, at least in size. I even tried it, I renamed the existing one in the MOI directory and put the newer one at the same place. Then I saved my MOI box3 file to skp format again and it basically look the same as before in SU.

My conclusion of this little experiment is that even if MOI can export to SU which may be very convenient and appreciated by some, for my own use it's not very useful as I'll most likely have models composed of many connected parts. If I still want to use SU I'll use obj format at this time.

Regards,
Felix
