Abstract
A three dimensional geometric modeling system featuring an executable program (400) allows a user to select and then drag and drop sheet metal solid shapes into a scene or assembly depicted on a display screen. The user selects the sheet metal solid shapes from a sheet metal catalog (300), thereby creating an instance of a program object for the selected solid shape. A program object (1302) for a sheet metal solid shape carries an application-specific or customized procedure (1000) which governs the drag and drop behavior of the sheet metal solid shape. Implementation of the application-specific or customized drag and drop procedure occurs upon detection of a special interface through which the program object for the sheet metal solid shape acquires environmental information. While some of the program objects for the sheet metal solid shape carry their own geometric profiles utilized for such CSG evaluation, program objects for other sheet metal solid shapes (such as the punch solid shape and the bend solid shape) instead rely upon a profile generator (415) to generate the profile at the request of the program object. The program also allows the user to edit table information utilized by the profile generator.
