No drawing is complete without text of some kind. The shapes on the **Annotation** tab enable you to easily add dimensions, plain text and leaders to your drawing. Simply drag and drop any of these shapes onto the drawing page. The **Controller Dimension** is an especially useful tool for managing your shape's dimensions. Refer to [*Working with Dimensions in Handset Designer*](/v1/docs/working-with-dimensions-in-handset-designer) and [*Working with Text Elements*](/v1/docs/working-with-text-elements) for more details on adding and editing these shapes. You can also see the video below for an overview of the purpose of each annotation. [Video](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/annotations.mp4)
