In modern manufacturing systems, the process of building a part from the Computer Aided Design (CAD) description is reasonably well established. However, the problem of starting from three-dimensional (3D) surface measurements of a part, and then building a geometric model of the same quality as the original CAD description, is an active research area. This paper discusses how to build geometric models that are properly closed. The fundamental problem is that there are gaps between the independent geometric surfaces that are extracted from the range data. This paper gives a solution to the problem of closing these gaps. Experimental results on closing the gaps for some basic examples using ACIS, a commercial object-oriented geometric modelling toolkit, are presented.
