Abstract:According to the current needs of steel structure engineering design and the characteristics of steel structure joint design, secondary development language Microsoft Visual Basic of CATIA was used to carry out the secondary development of CATIA, to develop 3D design software for steel structure joints. Based on the structural analysis model, the software designs and checks the steel structure joints, and combines the CATIA modeling features to create a 3D refined model of the steel structure joints in batches, enabling the rapid output of the analysis model to a more detailed physical model, which improves the design efficiency and quality. The overall architecture and key technologies of software development were explained in detail, and the applicability of the software was verified through two engineering examples.
Keywords:CATIA; secondary development; steel structure joint; refined model
