In this paper we discuss the requirements of common distributed CAD applications for an efficient and complete compression and decompression of 3D models. We give an overview of the state of the art methods in the field of geometric compression and present our solution, which combines and extens two existing approaches. Finally we present the results we obtained with our implementation and discuss the experience we made with different compression schemes.
