scale problem

When export draft sheet to Autocad we have notices that there is little differnce in scale.
Eg. 4500 in draft meassting 4121 in Autocad. Why this problem ? Please.

what export option file do you use?
If you export the dxf file at scale 1/1 and then scale the dxf in AUTOCAD it's a little difference.

Please let me know which option file to use and procedure to bring correct scale in Autocad.
we are using system DXF and Configurable dxf sometimes. Both option has same problem.

 

take the scale of the largest view. for example 1:100 and type the inverse as a scale factor in the utilities>dxf configurable options menu. When you do this, your graphics won't require rescaling in autoCAD.

Thanks to all, It is working. All I had a problem with a scale factor assigning.
