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. adding dimensions to a model, sectioning the model, obtaining a true shape etc. If dimensions (for example) have to be added to a model in a multi-view layout, then these dimensions should only be visible in the active viewport. This is also true for true shapes and sections.
