Abstract
A method, apparatus, and article of manufacture provide the ability to update a drawing surface in a CAD/GIS computer application. First, a drawing surface is displayed in a CAD/GIS application. A surface edit operation is then performed on the drawing surface. The CAD/GIS application then determines if an automatic rebuild option is active. If the rebuild option is active, the drawing surface is dynamically and automatically rebuilt to reflect the surface edit operation. Alternatively, if the automatic rebuild option is inactive (e.g., toggled off), the drawing surface is flagged as out-of-date.
