About Dimensioning the Model
Dimensioning the models in your drawings can be as simple or complex as required. To meet your drawing needs, you can:
Show driving 3D model dimensions, which maximizes model-drawing associativity.
Insert driven dimensions, which provides flexibility for repeating and nonexistent dimensions.
Customize the dimension display, which enables you to reformat and reposition dimensions.
Modify the dimension scheme
To take full advantage of the associativity between the 3D model and the drawing, your first drawing dimensions should be shown from the model (driving dimensions). Of course, there will be instances where you need additional dimensions to show the same value for the same object, for example, a view repeated on another sheet. You should insert driven dimensions in these situations.
 
* You can also add non-dimensional detailing, including geometric tolerances, symbols, and text notes.
