It has experienced decades that BIM (Building Information Modeling, referred to as BIM) is from a proposal to gradually improve, to the general acceptance of the construction industry. With the popularity of BIM applications in foreign countries, the application of the domestic construction industry is in full swing. The urgent need for standardization of BIM to construction of the related industrial chain link sharing and application of BIM. This paper introduces the design business owners, industry associations, research institutions and engineering companies BIM standard system state of progress of the construction industry for the domestic counterparts in the standardization of information and BIM to provide a reference.

3D modeling is one of the most primary features of BIM and Architecture CAD software. In this paper, we made a deep investigation into geometry kernels and modelers which are being used by current most popular and influenced BIM and Architecture CAD software. By evaluating, testing, comparing and applying three kernels, we got the suggestion and rules of using them, which could be a guide of designing and developing BIM software in the future.
