AutoCAD to BIM

If you’re an AEC industry professional, you must know the difference between the terms BIM and CAD. Building Information technology (BIM) and computer-aided design (CAD) are interrelated but they can’t be used interchangeably. The two terms have often been confused but they are not, it is important to know the difference between the two technologies.

What is CAD?

CAD is a computer technology that helps create designs and documents related to a project.  It allows the architects, drafters, engineers and artists to design accurate models. It is used to bring multiple designs together to accurately implement technical illustrations to the project. The CAD software can be used to create 2D (two-dimensional) and 3D (three-dimensional) models.Technology evolved, and more concepts are being introduced in the AEC industry. BIM is such a concept which has become eminent in the past few years because of its many benefits.

What is BIM? 

BIM is a promising way of changing the face of the AEC industry and making it truly digital. BIM makes it easier for architects to create digital models that provide information about the physical and functional characteristics of a building. It allows architects, engineers and stakeholders to bring together coordinated models and efficiently build infrastructures through digital modeling. All their different entities can be coordinated for better results.


Uses separate documentsBIM assembles all that information into one
The info which can lead to confusionsMore task-oriented approach
In CAD, we use 2D drafting& 3D modelsBIM draw buildings based on real-life properties
Elevations & Sections need to be made separatelyCreate a unified model that is great for modeling, clash detection and change management.
Chances of error are moreMinimizes the chances of errors in the design
Software used is AutoCAD etc.Software used in BIM is Revit, Navisworks,  etc.

Where to Use What? 

BIM or CAD’s requirement is unique and depends on an individual project. The AEC industry is inclined more towards BIM technology as opposed to 2D CAD Drawings. BIM is used for commercial buildings like airports, schools etc., while CAD is used for the Residential Construction, industrial design of mechanical and electrical assemblies.
