1. A method of operating a computer aided design system in presumptive mode, comprising the steps of: moving a selected graphic object relative to a graphic pointing symbol; determining when the selected graphic object is within a predetermined proximity of an underlying graphic object; manipulating the selected graphic object into a geometric relationship with the underlying graphic object according to predetermined geometric rules; and dynamically updating the geometric relationship based on movement of the graphic pointing symbol while the graphic pointing symbol remains within the predetermined proximity of the underlying graphic object.
17. The method of claim 1, further comprising the step of: unclinging the selected graphic object from the underlying graphic object to move with the graphic pointing symbol when the graphic pointing symbol is moved a greater distance than the predetermined proximity from the underlying graphic object.
