You can capture the quantities of objects that do not appear in the model using a virtual takeoff. Virtual takeoff takes advantage of viewpoints, formulas, measurements, and manual overrides. You can add a virtual takeoff to an existing Item, then associate a Viewpoint for that Item, which you can update and refer back to, make measurements and create markups. The camera icon in the Viewpoint field denotes the associated Viewpoint. Click it to view the Item in the Scene.
