Tekla platform-based power transmission iron tower BIM building method

The invention relates to a Tekla platform-based power transmission iron tower BIM building method. The method comprises the steps of 1) reading related model data and calculation result data of iron tower design and exporting a cross section library for Tekla platform format iron tower calculation; 2) importing the model data and the cross section library for Tekla platform format iron tower calculation to a Tekla platform, thereby generating an iron tower three-dimensional model; 3) performing combination and grouping on a same section of rod part in the iron tower three-dimensional model inthe Tekla platform; 4) adding all connection nodes to the iron tower three-dimensional model; 5) creating accessory members in the iron tower three-dimensional model; 6) performing space collision check on the iron tower three-dimensional model; and 7) inputting engineering information for parts in the iron tower three-dimensional model through the Tekla platform. According to the method, effective integration of power tr
