To Switch Dimension Format to Symbolic
When you click Tools > Relations, Creo Parametric switches the dimension display to symbolic format (for example, d0).
You can switch between symbolic and numeric dimension formats in one of the following ways:
In the Relations dialog box, click Utilities > Switch Dimensions.
On the menu bar, click Info > Switch Dimensions.
 
Tip: If dimensions are not already displayed on the model, select the feature or part whose dimensions you want to display.
 
* Symbolic tolerances appear only for dimensions with plus-minus or symmetrical formats. Other format types display only the dimension symbol.
