           <DetailedDescription>Should the auxiliary geometry representation be displayed as separate representation from model? If yes, a separate rendering pipeline will be created for auxiliary geometry and its representation will be controlled with its own set of display properties; if no, the geometry will be shown and controlled as sub-blocks in the model, which may be less flexible.</DetailedDescription>
