Abstract
A three-dimensional solid geometry modeling method is described that can move or modify any piece of solid or surface geometry, such as a protrusion or depression, when faces are changed in a way that is not obvious or predictable from the original data. The method involves a combination of local changes and a context-based process that uses simplification, detaching, modification, and reattaching algorithms. The method is invoked automatically when a modeling tool (such as Move or Pull) is used to move or modify a piece of geometry. During the movement or modification, the geometry reflects the changes dynamically as the user interacts with the modeling tool. When performing the modification, simplification of the faces and edges can be manually or automatically invoked.
