You can display a model parameter value with a tolerance. Select the Tolerance Value Only option in the Tolerance group of the Dimension ribbon tab, and set the required tolerance mode. Click the Dimension Text button. The Dimension Text panel appears. Specify the model parameter value as &PARAM_NAME:0, before the text string @D in the dimension text box. The resultant string in the text box appears as &PARAM_NAME:0@D. This causes the value of the parameter to appear instead of the dimension value, along with the tolerance value.
