Use the Custom Views panel-tab to create different views of your plans that you can reference during takeoff. You can select a portion of a sheet as a custom view and display it in a separate popup window that remains visible during takeoff. You can display multiple custom views at a time. The popup window contains a zoom bar, allowing you to change the magnification of the custom view as needed. You can adjust the size of the popup window and set it to remain on top of all other windows.
