A multiple representation allows the depiction of an item from another drawing in a detailed or alternate view. For example, a large vessel may be depicted on two drawings; one displaying the upper part and the other the lower part of the vessel. There is only one data record for the multiple representations, meaning that if you change one item of data, it is updated on all drawings. For data that is shown on labels on other drawings, they will be updated upon entering the other drawings or performing an update of out-of-date drawings. Until then the other drawings will be shown as out of date with respect to "Out of date model items".
