Click Maintain Relationships on the Relationships toolbar.
If the Relationships toolbar is not displayed, click Relationships on the Main toolbar.
You can also click Tools > Maintain Relationships.
When Maintain Relationships is set and you apply relationships to new or existing elements, the software places relationship handles on the elements. Elements that share relationships are associative; when you move an element, the other elements on the drawing sheet move according to the relationships they have with the element that you moved.
