You can use object anchors to attach an AEC object to the base curve of another AEC object. When an AEC object is anchored to another AEC object, it will be moved together with the anchoring object. When the anchoring object is deleted, the anchored object will be deleted, too. Changes that are made to the anchored object, however, will not be replicated in the anchoring object.
When the anchored object is selected, a temporary graphic displays the anchor. The temporary anchor graphic contains a trigger grip to release the object anchor.
