You can copy dimensions and annotations from a part, sheet metal, or assembly model to a drawing view using either of the following methods:
Use the Retrieve Dimensions command to copy dimensions and annotations from the model to an existing orthogonal or section drawing view. The Retrieve Dimensions command copies PMI dimensions and annotations as well as sketch dimensions and annotations.
To learn how, see the Help topic, Retrieve dimensions and annotations from the model.
Use the Drawing View Wizard to generate a drawing view from any previously defined PMI model view created with the PMI tab→Model Views group→View command. This method copies only PMI elements to the drawing.
To learn how, see the Help topic, Create a PMI drawing.
With either method, when you change the design later you can use the Update View command on the shortcut menu to update the part view and the retrieved dimensions also update. For example, if you change the size of a hole in your part, the retrieved dimension for the hole in the part view will update to the new value.
