From 2D To 3D: Computer Aided Architectural Design

90 years of the 20th century into the digital era, computer use on the building design industry has a huge impact, building professionals at all levels of penetration of digital technology in the figure. In the course of computer architecture design play an increasing potential.The architectural design industry in China in the computer aided architectural design (Computer Aided Architectural Design, referred to as CAAD) in the field, 2D CAAD technology and its applications, dominated, and the formation of the corresponding architectural design process. However, with the increasing complexity of architectural design, architectural design of this two-dimensional environment has been unable to meet the information needs of the community.Advanced computer technology and information technology bring higher demands, offer more advanced tools and methods as well. Taking full advantage of the software and hardware technology, applying with the developmental trend, adopt the most advanced technology means and software tools to improve Chinese architectural design level and increase the industry productivity, Which is an urgently problem.Although 2D CAAD applications can improve the efficiency of times and even drawing a few times, considerable benefits. But look at the design industry itself, the rapid development of today's society is, need shorter the time to make better designs, to enhance competitiveness; from the owners point of view, in hopes of investments are return; from social perspective, the building features will become increasingly complex and increasingly integrated. Therefore, the current design of the building will have a higher demand.Current construction problems with the design industry is the result of two-dimensional work environment is no longer appropriate to the current building design requirements. In order to solve these problems, you need to change the architectural design of the work environment.In architectural design, based on the "BIM" (Building Information Model, referred to as BIM) technology system provides us the opportunity to achieve three-dimensional design. "Building Information Model" to create a building that contains a lot of real information on the virtual building model, which contains a large number of building materials and building construction, technical and other information, including the construction of a building all the components needed."Building Information Model" for the realization of three-dimensional design of a technical basis, but to change the current plight of architectural design industry, also need to understand three-dimensional design of the building design impact. From the present situation of China's architectural design, in-depth analysis of our computer-aided architectural design problems. With the current building design industry's advanced technology, we proposed the design in three-dimensional environment behind. BIM and the application of our country were thinking, that hindered the development of BIM factors in China, put forward development proposals BIM.
