Hi Martin, are you sure the file you attached has units set to mm?

I tried importing it into a couple of other CAD programs like Rhino and ViaCAD and they both also seemed to think the units in the file were actually inches and not mm.

I seemed to get the same result in both of those other CAD programs as opening the file in MoI.

Is there possibly some setting for overriding units that you need to clear in the program that you're using to export this or something like that?
