Aggregate groups must be added to the plant tree below a plant in the hierarchy.
The following figure shows an extract from the available items in the aggregate group from the component library.

You can either use a blank template called Aggregate Group or one that already contains data, e.g. Gearbox - Motor 2 stage. In general, it is always advantageous to select the template that is as close as possible to the actual configuration to keep the amount of adjustment required to a minimum.
