Study on Arch Dam Visual Modeling System Based on CATIA

The paper bases on the idea of parametric modeling, used object-oriented technology, combined the parametric design and knowledge engineer system, to develop arch dam visual modeling system. System bases on CATIA V5 platform, to VB as a secondary development tools, utilizes database technology to support data exchange between the module and processing. Users through an interactive design parameters input, uses the system function to complete parametric modeling of arch dam, transverse joints division of arch dam, arch dam construction parameters extraction and engineering drawings automatically generated in line with the requirements of the design. It has certain practical value for Hydraulic Engineering.
