To Manually Attach an Element to a Task

Select the element(s) you want to attach to a task.
Drag the element(s) on the task to which you want it to be attached, in the Animation Producer dialog.
The element(s) are listed in the graph and in the tree pane as a subtask of the selected task.

Note: When you delete an element or named group, all the script entries that were created when you made the link are deleted.
