All objects have the date attribute "revision date". This attribute is automatically set to the current date when an object is added or the name is changed. The purpose of the revision date is to support updating network files using external data sources. The revision date has been added to all objects and is stored in the network file.
The revision date is automatically set to the current date if an object is added or if its name or ID is changed. With cables, also if the cable type or length is changed.
The revision date is shown in each object form on the Specials tab at the bottom right. If the revision date does not exist, nothing will be shown.
The revision date can be manually set or reset for a number of selected objects with Start | Edit Collective | Object.
Objects can be selected based on their revision date, with Start | Select | Special | Revision.
