One-Dimensional Topological Entities Matching for Heterogenous Data Exchange

In the process of feature-based data exchange (FBDE), one-dimensional topological entities are always used as references or operational objects in the source CAD system. To ensure FBDE, the corresponding one-dimensional topological entities in the target CAD system should be found to match the source ones. In this paper we describe in detail an algorithm for supporting the match for FBDE. The algorithm has been used in the procedure recovery architecture. It has efficiently improved the import algorithm used in the UPR.
