		<abstract>This paper deals with the problem of creating and maintaining a spatial subdivision, defined by a set of surface patches. The main goal is creating a library of functions which provides a layer of abstraction capable of hiding the geometric and topological problems which occur when one creates and manipulates spatial subdivisions. The study of arbitrary spatial subdivisions extends and unifies the techniques used in nonmanifold solid modeling.</abstract>
