Leapfrog Works - Export to CAD in Millimetres

Dear community, 

I exported a geological model in DWG format to our client who need to import it in their own model. 

unfortunately the client's unit system is millimetres whilst we produced our model in Metres. 

Is it possible to change the model unit system or export in another unit? 

Many thanks for your advice,

Best Regards 
Guglielmo
