Inventor files one tenth the size.

I just upgraded to Cura 3.4 but I was having the same problem with 3.1  I had been using Inventor 2016 to make my 3D models and exporting .stl files.  I remember I had this problem before and it was a simple checkbox or something like that but that was 3 years ago and I don't remember what it was or where to find it.  When I model something in Inventor(3 years ago in 2016 and fixed it) now the same thing is happening in the 2019 version of Inventor I just updated to. 

No matter whether I use inch or mm the .stl comes in one tenth the size 25.4 mm ( or 1 inch)  is 2.5 mm in Cura 3.1 or 3.4.  I recall there was a very simple fix but I can't recall what it was.  And no it was not make everything 10 times bigger. 

The fix was in Inventor as I recall because the same thing happened in Ideamaker and other 3D slicers.

When you export from inventor look at  options , most likely it exports as centimeters even though your model is in mm.

Was surprised to see this first time printing from inventor too.

At least it was not an export from Revit which uses Imperial measurement of 1' (12"). That would have made it really, really tiny ?
