ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to graphical user interfaces, and in particular, to a method, apparatus, and article of manufacture for providing positioning and alignment aids for software objects with authorable behaviors and appearances for computer programs having a graphical user interface.
2. Description of the Related Art
The use of Computer Assisted Drafting (CAD) application programs is well known in the art. Some CAD programs provide templates and palettes that help users create documents, graphical presentations, etc. However, these templates and palettes provide only limited assistance and do little to help the user connect standard CAD components, such as shapes and other objects, in the CAD document.
Many standard components have several connection points that can connect to other components. Typically, if a user wants to connect components together, the user must drag the components onto the working screen, and subsequently use toolbar accessed functions to move the component, rotate the component, or size the component in order to create a finished document or graphical presentation.
This multiple step approach of dragging the components onto the screen and then modifying the components to create a drawing is inefficient and time consuming. Further, the process is not easily learned by a user, and prevents many users from utilizing the CAD program to its fullest extent.
Consequently, there is a need in the art for improved techniques for connecting components in a CAD program, in order to create documents faster. Further, there is a need in the art for improved techniques for connecting components in a CAD program that eliminates the need for accessing toolbar or menu functions.
SUMMARY OF THE INVENTION
To address the requirements described above, the present invention discloses a method, apparatus, and article of manufacture for executing intelligent shape programming in a computer within a CAD application program, wherein the intelligent shape programming selectively displays informational aids associated with a displayed shape on the monitor of the computer to assist a user in manipulating the shape while operating one or more functions of the CAD application program. When invoked, the intelligent shape programming displays plugs and sockets on the monitor related to the selected shape and the target shape, and aids the user in connecting the selected shape to the target shape.
This instruction is accomplished by the intelligent shape programming executing a predefined sequence of steps to perform the selected task. The intelligent shape programming also monitors the user's interaction with the CAD application program during execution of the sequence of steps.
