skp to dxf/stl changes measurements



I downloaded the extension to convert skp to dxf/stl. I convert 2D objects to make them good for laser cutting. When I view to converted file after, the measurements have changed even though I choose millimeters like when I created the models.  When I convert to stl, it reduces size ca 10%. When I convert to dxf, it increases the size ca 20 x. 

I did the suggested steps of putting the skp to parallel and top view before converting. I also checked model info, all is in mm.

Please help!

Thanks for reporting this. Please can you send me an example Sketchup file and the corresponding exported STL file? Send them to [email protected]. Also let me know what version of Sketchup & what operating system you are using.
