New users to Revit often struggle to understand the concept of View Range.
View Range Explained
Every floor plan and Reflected Ceiling Plan view has a view property called View Range,
Once you are comfortable in controlling the various parameters contained within the View Range control panel, you’ll be able to easily manipulate exactly what is displayed in your Plan & Reflected Ceiling Views.
View Range Dialogue
The following image shows the view range of a plan view from an elevation view standpoint.
The horizontal planes are Top, Cut Plane, and Bottom. The top and bottom clip planes represent the topmost and bottommost portion of the view range. The cut plane is a plane
that determines at what height certain elements in the view are shown cut. These 3 planes define the primary range of the view range.
View depth is an additional plane outside of the primary range. You can set the level of view depth to show elements below the bottom clip plane. By default, it is coincident with the bottom.
Elements outside of the view range do not display in the view. The exception to this is if you set the view underlay to a level outside the view range. For more information on the Underlay view property.
