To Overwrite Dimension Value Display with a Text String
Use this procedure to replace a driven dimension value with a text string. Driven dimensions update with changes made in the 3D-model, but they cannot be used to modify the 3D-model from the drawing interface.
1. Select the dimension to modify. The Dimension ribbon tab opens.
2. Click the Dimension Text button. The Dimension Text panel opens.
3. In the dimension text field, replace the symbol @D with @O and type the text you want. The symbol O represents overwrite; anything you type following this text overwrites the dimension value. The drawing now displays the text string instead of the dimension value.
 
• Dimensions must always have a displayed value. If you do not type any text after replacing @D with @O, the system retains the dimension value of the selected dimension. In case of a reference dimension, if you do not type any text after replacing @D with @O, the system retains the value of the selected reference dimension and does not display REF.
• You cannot overwrite dimension values for driving dimensions. If you replace @D with @O and type the text you want for a driving dimension, the dimension value is not overwritten. Instead, the text is appended to the displayed dimension value.
