Convert .ipt to .stl in 2017 inventor

[Anonymous]

I am using inventor 2017 to convert an .ipt file to an .stl file.  When I convert the file the dimensions suddenly change but there don't seem to be any options when I go to export it as an .stl file.  Why is this happening and how can I make sure that dimensions/units aren't changed after I convert the file?

File>Save Copy As>Type *.stl and click Options.

Before you press the save button hit the Options button right next to it and set the units to what your 3d printer expects..

Hit this button..

Then this will open..
