WHen i bring stuff over from another Cad/Cam package i use, even though it was set to "Inches" in the other package, it comes in as "Millimeters" and the object is very huge in the viewport... I first change the model back to inches and it drops back down to size again....

We have discussed this before Michael. Something about the other app (which I believe is working with mm as a native internal unit) that doesnt transfer over properly....

FYI
