You can create elevations of the building models in your drawings by first drawing an elevation line and mark, and then creating a 2D or 3D elevation based on that line. You can control the size and shape of any elevation that you create, and you can update an existing elevation when the objects included in the elevation are modified. 2D elevations are created with hidden and overlapping lines removed. You can control the appearance of 2D elevations by applying rules that are controlled by the style and display properties of the 2D elevation.
