ABSTRACT:
A region defining technique for use with a computer aided design system, including a geometry specification step and a loop-chasing step which together locate the complete set of sequences of linked elements which defines the inner and outer boundaries of the region of interest in response to a single user input identifying which region is of interest. The technique permits a user with a single "pick" to select a desired region of the display for further processing such as cross-hatching or extrusion, and provides a variety of useful applications not previously offered in commercially available computer aided design systems.
