A mass element or a mass group consists of a number of display components that can be determined by materials.
You assign one material to each display component of the mass element or mass group. For example, you assign a dark wood material to the mass element body and a light brown material to the mass element hatch. When you assign a material to a mass group, the display properties of the attached mass elements are overridden with the mass group settings.
If you want to use the display properties of the mass element instead of the material display properties, you can deactivate the material assignments in the display properties of the mass element.
The display properties of an object are specified for each display representation individually. Mass elements and mass groups have display representations for plan, model, reflected, and sketch views. You can create new display representations for mass elements and mass groups by copying an existing representation. For example, you can create a new display representation “Plan 1:25” to create a plan view optimized for display in a view scaled to 1:25. This new display representation has the same display components as the one from which it was copied. The copied components will be influenced by the same material components as the original components.
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 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 mass element components and the material components that determine them.
