Dimensions different from Autocad export

Drawing dimensions change when I save from Autocad (DWG or DXF) and open in Shaper3D.

I have created a drawing in Autocad mechanical 2018 and the dimension of a particular object is 10mm. When I open the file in Shaper3D, that same object is 254mm…?
I have tried saving and opening the drawing as DXF and DWG, however I get the same results.

Is there a way to save a file from Autocad and then open in Shaper3D so that object dimensions are the same as in the original drawing?



For me it seems like a mm to inch change during export. This page will probably help. Let me know if it solved the problem:
