Understanding the differences between BIM and CAD
In simple terms, when using CAD for building design, you focus on creating drawings. When using BIM, you focus on creating a building model and then the drawings can be generated from the model.
What is BIM?
BIM is Building Information Modeling. It is an intelligent 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to efficiently plan, design, construct, and manage buildings and infrastructure.
What is CAD?
CAD is Computer-Aided Design. CAD software provides technology for architects, engineers, and construction professionals to design and create precise 2D and 3D drawings, replacing manual drafting with an automated process.
What's the difference between Revit and AutoCAD?
The biggest difference is that AutoCAD is a CAD software and Revit is software for BIM. While AutoCAD is a general drawing tool with broad application, Revit is a design and documentation solution, supporting all phases and disciplines involved in a building project.
Revit is used to coordinate all data inputs (including CAD) and produce federated project deliverables. Both programs are often used within the same firm, with BIM and CAD specialists working on different elements of a project.
