The program’s unique View Filter feature lets you decide which elements or locations you want displayed at any given time. For example, you may want to hide your roof and ceilings to be able to see inside the model. It also lets you make selected elements non-selectable, which is sometimes necessary when trying to select a particular element in your drawing, like a floor or ceiling.
