At present, most structural designs of light-weight steel framing system are still applying traditional methods of 2D CAD drawings and standard atlas, which will certainly fail to meet the needs of digital design and intelligent construction in the future. According to the structural form and characteristics of the light-weight steel framing system, this paper proposes a parametric structural design method of the light-weight steel framing system through BIM application, considering the relevant design specifications of cold-formed thin-walled steel. A special design module is also achieved through the Revit API technology programming to realize the core functions including automatic layout of light steel keel, automatic drawing, output of detailed report of quantities, and etc., which provides references for the realization of intelligent design and intelligent construction of the light-weight steel framing systems.

The demand for BIM talents is increasing gradually, while they are facing challenge of both BIM technology and professional development. The author tries to research the facts which affect the long-term personal development for occupational environment of BIM field.
