ABSTRACT
Viewport specific layers When layers are used with multiple viewports they are generally GLOBAL, i.e. what is drawn on a layer in one viewport will be displayed in the other viewports. This is quite acceptable for creating models but is unacceptable for certain other concepts, e.g. when dimensions have to be added to a model, or if the model is to be sectioned. If dimensions are to be added to a multi-view drawing, then these dimensions should only be visible in the active viewport.
