A 2D or 3D elevation object consists of a number of display components that can be determined by materials. When you assign materials to an object, you assign one material to each display component of the object. For example, you assign a wood material to the frame of a window and a glass component to the glass of a window.
When you create a 2D or 3D elevation object from building objects, the material assignments of the source objects are applied to the elevation. You do not assign a material directly to a 2D/3D elevation. The elevation takes its material assignments from the objects. For example, if you create an elevation of a wall with a window, the surface hatches you have defined in the glass, wood, and brick materials of the wall and the window are displayed in the elevation object.
If you do not want to use the material display properties, but instead use those of the 2D or 3D elevation object or the 2D elevation style, you can deactivate the material assignments in the display properties of the elevation or the elevation style.
Material definitions consist of display components that correspond to component types of objects. For example, the Linework component of a material is used for all linework of objects in Plan view. The Surface Hatch component of a material is used to hatch all object surfaces in 3D model views and elevations.

The following table lists elevation components plus information about the material components that determine them.
