Modification of the dwg-dxf / export option

Hello

I would like to modify the 1:1 output scale option because on several workstations this option is not checked by default and I do not want to remove the customization of each artist.

Is there a solution via macro to activate this 1:1 scale (definitively or not) (N°1)

And another solution to change the scale of the view or sheet (N°2)

Thank you

 

For the 1:1 scale I just found:

swApp.SetUserPreferenceIntegerValue swUserPreferenceIntegerValue_e.swDxfOutputNoScale, 1

If anyone has the 2nd.-> EDIT: not possible see the following link:
