Figure 3 - Editing the Elbow Display You can create Datum Feature Symbols on planar or cylindrical geometry.

The 5_Datums combined state is typically used to display the datum feature symbols.

Use the following process to create Datum Feature Symbols on geometry:

Click Datum Feature Symbol from the Annotations group in the ribbon.
Select the desired planar or cylindrical surface on which to place the datum feature symbol. The plunger is created at that pick point location.
Drag the cursor to extend the label and middle-click to place the datum feature symbol.
Edit the name as desired from the Label group in the ribbon. The system automatically labels the datum feature symbol the next incremental alphabetical label, but you can type your own desired label in, too.
Add semantic reference surfaces as appropriate.
Configure any additional options as necessary.
