Thanks for the reply.

I am using V2. I have checked this option.

when I bring it into modo and I make a 900 meter box as reference, yes imported model fits within it exactly.

However my model in SolidWorks and Moi measures 900 INCHES.

With this option checked and unchecked, the model comes into modo at the same size. The only way to fix this is to scale it down to 2.54% of its original size.
