ABSTRACT
An extended rounding operation can be an excellent tool for modeling solids with free-form surfaces. Using the rounding operation, the edges and vertices of a solid can be locally rounded, and those parts of the solid are changed to free-form surfaces. As a user, you put in information about edges that should be rounded and the radii of curves generated by the operation. This facility has been implemented in our solid modeling system, Desiqnbase.
