Just a dumb idea but I figured I'd throw it out there. Have you tried making a very small model in MED and bringing it into WED? Conversely, have you tried making a big model in MED and bringing it into WED and using its scale property to make it small? I'm wondering if one of the two methods above have different effects on the engine or if it really amounts to the same thing as far as A5 is concerned. Hmmm.
