Abstract

An intelligent shape is displayed in conjunction with a CAD application program, wherein the intelligent shape can be authored by a user. The intelligent shape comprises a frame and at least one property which defines the shape. The intelligent shape comprises several objects for use in connecting, manipulating, displaying, mapping, and otherwise creating a new component or modifying an existing one. The intelligent shape also monitors the user'"'"'s interaction with the CAD application program during execution of the sequence of steps, wherein handlers defined for the shape provide additional customization of the component shape during system operations.

Claims

1. A method of creating a shape for displaying information on a monitor attached to a computer, comprising the steps of:

creating a spatial frame of the shape wherein the spatial frame provides a mapping function between an inside of the shape and an outside of the shape and provides a geometric framework for the shape;

creating at least one property of the shape;

coupling the property of the shape to the spatial frame of the shape, wherein the property couples to the geometric framework of the spatial frame; and

modifying the property coupled to the spatial frame to display desired information on the monitor without displaying the spatial frame on the monitor.

2. The method of claim 1, wherein the property of the shape is selected from a group comprising entities, plugs, sockets, handles, custom properties, drag handlers, and message handlers.

3. The method of claim 2, wherein the entities of the shape contain at least one additional shape.

4. The method of claim 2, wherein the step of coupling further comprises the step of coupling the second object to the first object along a defined range of one or more of the attachment points.

5. The method of claim 2, wherein the entities comprise a geometrical construct for rendering the shape'"'"'s appearance.

6. The method of claim 2, wherein the plugs comprise a first side of a connection point for the shape, the first side of the connection point defining where the shape can attach to other shapes.

7. The method of claim 6, wherein the plugs further comprise a first side of a logical connection point for the shape.

8. The method of claim 6, wherein the plugs further comprise a first side of a geometrical connection point for the shape.

9. The method of claim 2, wherein the sockets comprise a second side of a connection point for the shape, the second side of the connection point defining where other shapes can attach to the shape.

10. The method of claim 9, wherein the sockets further comprise a second side of a logical connection point for the shape.

11. The method of claim 9, wherein the sockets further comprise a second side of a geometrical connection point for the shape.

12. The method of claim 2, wherein the handles comprise at least one point located within the shape, the point being exposed to a user interface when the shape is selected.

13. The method of claim 12, wherein the handles allow direct manipulation of geometry within the shape.

14. The method of claim 2, wherein the drag handler comprises at least one object that controls a behavior of the shape during a drag operation by a user.

15. The method of claim 2, wherein the message handler comprises at least one object that controls a behavior of the shape in response to a system event of the computer.

16. The method of claim 1, further comprising the step of modifying the spatial frame to display desired information on the monitor.

17. A computer-implemented apparatus for displaying information, comprising:

a computer having a monitor attached thereto;

means for creating a spatial frame of the shape wherein the spatial frame provides a mapping function for the shape and provides a geometric framework for the shape;

means for creating at least one property of the shape;

means for coupling the property of the shape to the spatial frame of the shape, wherein the property couples to the geometric framework of the spatial frame; and

means for modifying the property coupled to the spatial frame to display desired information on the monitor without displaying the spatial frame on the monitor.

18. The computer-implemented apparatus of claim 17, wherein the property of the shape is selected from a group comprising entities, plugs, sockets, handles, custom properties, drag handlers, and message handlers.

19. The computer-implemented apparatus of claim 18, wherein the entities of the shape contain at least one additional shape.

20. The computer-implemented apparatus of claim 18, wherein the means for coupling further comprises means for automatically coupling the second object to the first object along a defined range of one or more of the attachment points.

21. The computer-implemented apparatus of claim 18, wherein the entities comprise a geometrical construct for rendering the shape'"'"'s appearance.
