Linking Objects Interactively

To link objects in the Working window:

Select the object you want to set as the child object. A series of icons appear next to the object's bounding box. The icons along the right side of the object's bounding box let you interactively link objects.
Click the Link icon and drag the linking line to the object you want to use as the parent object. You cannot create a link where the parent object is the child of its own child object (i.e. a loop). The parent object turns blue.

The first object you select becomes the child object. The object you drag the link line to becomes the parent object.
