Software-based steel member approach statistics and drawing marking method

The invention relates to a Tekla-CAD (computer-aided design)-based steel member approach statistics and drawing marking method. The method comprises the following steps: step 1, providing a steel structure layout drawing by adopting Tekla; 2, arranging an existing component list; 3, extracting information of component numbers in the layout diagram by adopting CAD (Computer Aided Design) and importing the information into EXCEL; the information of the present components is imported into the CAD steel component arrangement diagram at one time by adopting Text, namely a single-line character command and is operated, so that the present components can be clearly displayed in the arrangement diagram, and the components with colored fonts are the present components. According to the steel member management method provided by the invention, all on-site members can be marked on the layout diagram at one time, the on-site member management and control are facilitated, and the accuracy of marking is also improved by ad
