Object Styles

During my presentations I frequently meet dismay on architect's faces, when I tell them Revit do NOT contains Layers. The reason is that we do not need them at all, and this is a fact.
Objects (Components) know their kind (Category) and the appeas as they should in all Views.

Not only the Components, but all of their 2D and 3D sub-elements, lines and forms (Sub-Categories) have clear look. To every Category you can add sub-categories, if necessary.
In the row of the table above you can set the exact face of every Category in Cut and Projecion. The Material defines the cut-fill of the 3D components in plan and section views.
These setting are valid in the whole project and can be saved to templates. This global setting can be overwritten by Views in the Visibility/Graphics dialog.
