In this study, mainly based on BIM technology, I analyze the application of BIM technology in structural design of constructional engineering respectively from field data analysis, structure parameter design, interior design and professional coordination design, and analyze the application effects of BIM technology in structural design of constructional engineering by combining practical cases, which is expected to serve as the effective theoretical basis for the improvement of structural design of constructional engineering in China.展开更多

In the process of transmission, it has a lot of data and pro^ams, thus, facing the audience groups of accepting different information ability, it often appears information transmission distort or misunderstanding. Information visualization design will represent a lot of agricultural science and technology information with complex structure and level, making use of the graphics relationship, by using the concise, easily browsing and searching method. How to make use of the information visualization design to solve the large capacity structure of agricultural science and technology information is the content that this paper analyzes.展开更多
