The main difference is that AutoCAD is a general computer-aided design and drafting software used to create precise 2D and 3D drawings, and Revit is software for BIM (building information modeling) with tools to create intelligent 3D models of buildings, which can then be used to produce construction documentation. While AutoCAD is a general drawing tool with broad application, Revit is a building-specific design and documentation solution, supporting all phases and disciplines involved in a building project. Both programs are often used within the same firm and even by the same practitioner.
AutoCAD and Revit are interoperable and can be used together, for example, to incorporate designs created in AutoCAD within a Revit project. Firms may use AutoCAD on some projects or components of a design and use Revit to generate BIM deliverables and to enable collaboration with other design disciplines.
