When exporting a drawing to DWG the ordinate dimensions are moved in the positive 'Z' axis by 0.1mm. What is the issue and can it be fixed? I've tried changing the units to inch with no luck; it moves the ordinate dimension in the 'Z' by 0.004". All other dimensions have a 0 'Z'. All the geometry, center lines, and GDT, etc...have 0 for 'Z'.
