Tutorial Automatic Naming of Datum Feature Symbols in Detailed Drawings

When creating a datum feature symbol, the next available name in the standard sequence (A, B, C, and so on) is automatically assigned. You can change the label at any time from the Datum Feature tab. If a datum label in the sequence is missing, the next datum feature symbol to be created will fill that gap. The datum labels are checked to make sure they conform to the conventions specified by the ASME Y14.5 standard. The label must be either one or two uppercase letters, and the letters O, Q, and I are not permitted. Datum feature symbols that violate these rules are identified in the user interface by a red wavy underline in the box where you type the label name and in the graphics window by a red underline in the annotation. If you place the pointer over the red wavy underline in the ribbon, a message appears describing the error.
