Simplify3D User Forum

Hi. A 3D designer use Inventor and export a file as STL, and he sent me the stl file for 3D printing.
So I opened it with Simplifiy 3D, but size (XYZ) is very strange. It is much much smaller than what he designed.

Is there anyway to fix it ?

It probably means they did not export the STL file in millimeters. Perhaps they used inches or centimeters instead. In that case, you need to scale by 25.4x or 10x.
