The general rule for scoping is that when selecting items, the software automatically scopes all the related items and all the items that extend up to and including the item power source. For example, selecting a motor that is connected to a feeder circuit, the software will scope the motor control stations, the motor feeder cable, the feeder circuit, the bus, and the PDB.
You can automate the process of scoping plant items by scoping a composite drawing. Once a composite drawing is scoped, all the plant items that are associated with graphical elements on the drawing are scoped automatically. Furthermore, the parent items of those plant items are also scoped automatically even if the parent items are not on the scoped composite drawing.
The extent of the related items that are scoped along with the main selected item are indicated in the following table.

When scoping an item that is connected in parallel with another equipment item, the software automatically scopes all the items that are connected in parallel to the scoped item. For example, if you select Motor-1 that has been connected in parallel with Motor-2 and Motor-3, the software will also automatically scope Motor-2 and Motor-3 together with their upstream items all the way to their power sources.

You can scope the same item for more than one project.
