Abstract:

To meet the requirements of the largescale engineering systems which need a parametric rapid design system for the combined structural sections. A system of parametric drawing for the combined structural sections has been designed and developed. The system based on the technology of the parametric design and the database of The Tianyu Part Library to draw a single structural section crosssection graph and transform the graph through a series of transformation matrices to get the combined graph.With a special blanking algorithm to support, the system achieves the projection view of the horizontal and vertical directions of the combined structural section by the combined graph’s database. This paper analyzes the system’s framework, and introduces the key technologies involved, such as the structural section of the combination, the location view of the structural section and the blanking algorithm of the projection view. An application example in a boiler enterprise is given.
