Precision control

 From:  BurrMan

I am importing a MoI model into my cad package. If I make a 5 inch Sphere in MoI it has a size of 5.0020 in the Cad side.

Is there a setting in MoI that is controlling the level of precision?

If not, My next question would be the same to the Cad people.

Thanks,
Burr
