Abstract: An intelligent shape is displayed in conjunction with a CAD application program, wherein the intelligent shape selectively displays positioning and alignment aids on the monitor of the computer to assist a user in operating one or more functions of the host application program. When invoked, and a first object is positioned proximate to a second object on the monitor, plugs of the first object are displayed on the first object. The plugs indicate one or more respective attachment points on the first object. A socket is created on the second object when the plug of the first object is placed proximate to the second object. The socket indicates an attachment point between the first object and the second object. The first object and the second object are automatically coupling together at the attachment point.

Abstract: A connector object supports bi-directional connections such that an instance of the connector object may behave as both a socket connector and as a plug connector. A first shape object and a second shape object having a first connector object and second connector object respectively that are instances of the same connector object are displayed on a display device. The first connector object is coupled to the second connector object wherein the first connector object and the second connector object behave both as sockets and plugs. An external connection manager resolves connections. The manager determines: (1) if shape connections should be resolved; and (2) one or more socket connector objects and plug connector objects that need to be updated from one or more other shapes coupled to the determined socket connector objects. Thereafter, the manager recursively updates each determined plug connector object.

Abstract: A method, apparatus, and article of manufacture for creating a shape for displaying information on a monitor attached to a computer is disclosed. The method comprises the steps of 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, creating at least one event handler of the shape, coupling the event handler to the shape, and using the event handler coupled to the shape to display desired information on the monitor.
