Our company has a special design department and R&D department, and has established an independent and perfect steel structure engineering design, optimization and deepening design system. In the process of modeling, every column, beam, bolt and weld of the whole project is designed into the model according to the actual size of the building. The three-dimensional model can rotate arbitrarily at 360 angles, any part and any node can be pulled close and enlarged, and the intuitive effect is exactly the same as the actual situation. Thus, the possible problems in the two-dimensional graphic design drawings can be solved and handled in advance. Then automatically numbering each part board and each component, directly generating layout, component drawing and part drawing, so as to ensure seamless docking between factory manufacturing and field installation, and ensure accuracy and efficiency.
