Description

Technical Field

[0001] This invention relates to the field of steel structure detailed design technology, specifically a method for rapidly generating change reports for steel structure BIM models in Tekla. Background Technology

[0002] In building construction, the BIM model for detailed steel structure design serves as the foundation and basis for guiding the entire construction phase of a steel structure project. Changes are inevitable in detailed design work, and these changes often have far-reaching consequences. Change handling is a major pain point in detailed design work. Manually processing and compiling change information is complex and tedious, and compiling the change results into drawings is time-consuming and prone to omissions or errors. The typical change handling time is twice or more than the normal modeling and drawing process. For example, if the normal modeling and drawing process takes 2 hours, manually processing the changed model takes 1 hour, compiling the change results takes 1 hour, and writing the change results into drawings takes 0.5 hours, for a total change process of 2.5 hours.

[0003] Tekla automatically generates steel structure details and various reports after a 3D model is created. Since the drawings and reports are based on the model, and the operator can easily identify errors in the connections between components within the 3D model, it ensures the accuracy of component connections in the detailed design of the steel structure. Simultaneously, the various reports and interface files (CNC cutting files) automatically generated by Xsteel can serve (or be used directly on the equipment) throughout the entire project. Tekla Structures' functions include full integration of 3D solid structural models and structural analysis, 3D steel structure detail design, 3D reinforced concrete design, project management, automatic shop drawing, and an automatic BOM generation system.

[0004] Patent document CN118071922A discloses a method for detailed design of steel structures based on Tekla, including: Step S1, providing steel structure design drawings; Step S2, using Tekla Structures software to perform detailed design based on the steel structure design drawings, generating detailed construction drawings of the steel structure through three-dimensional modeling; Step S3, if structural changes occur, modifying the three-dimensional model of the steel structure in conjunction with the changed structural design drawings, updating the steel structure design drawings after the three-dimensional model is modified, issuing a construction detail change notice and updating the drawings; Step S4, reviewing and providing feedback on the detailed construction drawings of the steel structure.

[0005] Patent document CN110059424A discloses a method for extracting processing information of steel structure modules based on Tekla software, including: constructing a three-dimensional model of a large steel structure based on Tekla software; copying a pre-configured Template file into the model folder of Tekla software; generating a drawing list, including at least a component list, a parts list, and a bolt relationship table, sequentially using the Template file in Tekla software based on Excel formulas and VBA language; converting the generated report file to .xls format; overwriting the folder where the automatic report program is located with the converted .xls file; opening the MarkList in the automatic report and entering the content into the project table, which must include at least project information and date.

[0006] When Tekla's BIM model undergoes changes, the process of compiling the content is complex and still relies on manual verification. It is time-consuming to compile the changes into drawings, and data statistics are prone to omissions or errors.

[0007] Therefore, providing a method for rapidly generating change reports for steel structure BIM models in Tekla is a problem worthy of research. Summary of the Invention

[0008] To address the challenges of complex content statistics, time-consuming data compilation into drawings, and data omissions or errors during traditional manual processing of Tekla BIM model changes, this invention provides a method for rapidly generating change reports for steel structure BIM models in Tekla.

This device will perform three steps. Step 12) The operator reviews the change report generated by the software, confirms the final change report, and the change processing work is completed.
