You can group annotations or parts together. Groups may consists of a single dimension, multiple text elements, parts, and multiple symbols. Each group has one of its elements as the master element.

Creo Elements/Direct Drafting creates one invisible refline between each element in a group and its master element. These reflines can be shown with either the SHOW_INV_RTL or SHOW_INV_GEO command. Deleting an invisible refline deletes the group. You can change the flyby highlight color of the group box and of the group master element with the FLYBY_GROUP_MASTER_COLOR function.
