### Overview

The Duct Description function adds duct annotation labels at all connector points.&#x20;

In the settings, you can select the requested annotation element from the list - for circular and rectangular ducts, or you can apply the labels to all elements in the view or just to the selected ones.&#x20;

You can also select the label insertion style - left, right, both ends, etc.
