To Convert Diameter Dimensions to Linear Dimensions
You can convert a diameter dimension to a linear dimension, or convert a linear dimension that denotes diameter of a geometry, to a diameter dimension without switching the view. When you switch views for one of these converted dimensions, initially the dimension appears in the format prior to the conversion, followed by the converted format type, and finally in its original displayed view.
1. Select the diameter dimension to convert to linear.
2. Right-click and click Show as linear on the shortcut menu.
Alternatively, click the Display button on the Dimension ribbon tab that opens, and select the Linear option in the Configuration list on the Display panel.
 
* You cannot convert a linear dimension such as, the depth of an extruded slot to a diameter dimension.
