Building information modeling（BIM）

Building information modeling (BIM) is the foundation of digital transformation in the architecture, engineering, and construction (AEC) industry. As the leader in BIM, Autodesk is the industry's partner to realize better ways of working and better outcomes for business and the built world.

What is BIM ?

It is the latest evolution of the building industry and it refers to the process of designing, builing and operating a building colaboratively using a singlecoherent system of 3D models rather than separate design drawings. Bl% incorporates people and technology to streamline time and cost, and improveefficiency in builds including skyscrapers, hospitals, office and residential buildings.

BIlM isn't just a set of sofware or simply a 3D model. t contains not only the model elements but the vast amounts of information that make up theproject, as well as the process of exchanging that information with other parties involed. Whereas previous workflows reled on multiple file formats andcisconnected processes that quickly became out of sync when changes were made, Bli worktlows alow for a much more dynamic and synchronisedapproach to project management.

What are BlM Levels?

Diferent levels of BlM can be achieved for various types of prjects. Each level represents a diferent set of criteria that demonstrates a paricular levelof'maturity. BlM levels start with 0 and go to 4D, 5D, and even 6D BlM. The purpose of these levels is to gauge how effectively, or how muchinformation is being shared and managed throughout the entire process.

So what does each level involve, and how can you idenify which at which level you're working? Below are brief descripions of the first three levels andan explanation of what criteria is involved at each stage.

what's difference between BIM & CAD?

BlM and CAD can both play powerful roles in construction projects. Their applications can overlaput they also diverge quite a bit.CAD is more of a multi-discipline design tool, usable for everything from building designs tomachinery and furnishing. So while CAD software can be used to design toys and equipment, it canalso be used to draw up the floor plans and models of an architectural project.
