Considering no construction analysis oriented software for long-span space structures exists in the domestic engineering software market in China, a constructionmodule is developed upon the platform of MSTCAD, a famous domestic software for space grid structures design. This will not only enhance the software functions, but also meets the growing domestic demand for construction analysis software.
