What is the difference between 3D CAD

Modelling and BIM?

The difference between 3D CAD modeling and BIM is that,

while both processes provide geometric expressions of

buildings and infrastructure, the BIM process goes beyond

geometry to capture the relationships, metadata, and

behaviors intrinsic to real-world building components.

Combined with technology of the BIM ecosystem, this data

drives improved project outcomes in a way that (non-

intelligent) 3D modeling cannot.
