Note:
  • The default units do not apply to imported geometry such as STEP files. Those files will default to 'Metric' and will need to be modified using the second solution from the list.
  • This setting will be applied to all units (meters will be changed to cm, kg to g, and so on). Alternatively for the mass unit, when creating a drawing with a Parts List, use the Unit option to change it separately.
