moving the representation of one of the first and second graphical objects on the display device in response to a value change of a property of said one of the first and second graphical objects, the value change of the property being automatically, without user interaction, communicated from an automated component across a network and received by the computer system, the property being associated with positioning of the representation of said one of the first and second graphical objects on the display screen, and automatically moving the representation of the other one of the first and second graphical objects joined therewith so that the representations of the first and second graphical objects emulate a mechanical connection of the representations.

8. The method of claim 7, wherein one of the graphical objects includes an anchor property, a value of the anchor property corresponding to the relative pivotal position of said one of the graphical objects to an anchor point of said one of the graphical objects associated with the joining of the graphical objects to one another.

9. A method of operatively joining two or more graphical objects graphically displayed on a computer display device of a computer system which includes the computer display device, a processor, and memory, the method comprising the steps of:

determining a relationship between two physical components based on a physical proximity factor and a physical connection factor;

providing first and second graphical objects in an object-oriented environment and storing the graphical objects in the memory of the computer system;

graphically display representation of the first and second graphical objects on the display device;

enabling a user to adjust the orientation of the representation of the first and second graphical objects relative to one another during a design state by operating a pointer device operatively connected to the computer system so that the orientation of the representations of the first and second graphical objects graphically represents the physical proximity factor;

enabling a user to selectively position an anchor point of one of the first and second graphical objects onthe display device by operating a pointer device so that the anchor point graphically corresponds to the physical connection factor of the two physical components relative to the representations of the first and second graphical objects;

effectuating a change of value in properties of said one of the first and second graphical objects that represent the position of the anchor point relative to the representation of said one of the first and second graphical objects based on the selected position of the anchor point by the user;

communicating data across a network connected with the computer system via a server automatically, without user interaction, to receive data from an automated component where such data corresponds to a position change of one of said graphical objects; and

moving one of said graphical objects during a runtime state in response to its receipt of said data corresponding to a position change and correspondingly moving another one of said graphical objects through its pivotal connection through the anchor point.

10. The method of claim 9, wherein said one of the first and second graphical objects includes an anchor property, a value of the anchor property corresponding to the relative pivotal position of said graphical object on its anchor point.

11. The method of claim 10, wherein the value of the anchor property is in the range of 0 to 360 degrees.

12. The method of claim 9, wherein the first and second graphical objects are each comprised of a plurality of other similarly configured graphical objects operatively connected together.
