User-defined views (angles of view, zoom settings, etc.) make the results evaluation easier. By using "visibilities", you can divide the model into user-defined and generated partial views that fulfill certain criteria. It is thus possible, for example, to only activate the surfaces of a plane or members with a particular cross-section for the display. Of course, you can use these options both for the evaluation of results and for the input of model or load data.
