Abstract
This paper extends a previously proposed algorithm for the intersection of finite-element surface meshes. The new version of the algorithm treats special cases of multiple intersections that were not dealt with in the original version. This paper also describes a class library, in the context of Object Oriented Programming, for the generic handling of several types of surface geometry. This library is incorporated to a geometric modeler, allowing its use for modeling complex models.
