DRF Is Not Referenced
This datum reference frame (DRF) is not referenced by any geometric tolerances. Although this is technically OK, an unreferenced datum reference frame may cause confusion for downstream users of the model. It is generally good practice to remove the unreferenced datum reference frames from the model. To do so, right-click on the DRF in the Feature Tree and select Delete from the context menu.
