DXF export of Contours don't scale or fall on project??

I created my contours from my project with GCP and when I exported the contours in a DXF format and insert into autocad it shows up in another world and scaled to some unknown factor.

Any help.


In my project, in the DXF header, INSUNITS is set to 2 (Inches), I change it to 0 (unitless) and it comes in fine.
