Difference between CAD & BIM
What is CAD?
CAD CAD or or computercomputeraided aided design design facilitates facilitates design design & & documentation documentation through through computer computer technology. technology.
Engineers Engineers implement CAD for implement CAD for multiple multiple components components to fit in to fit in a a large large assembly. assembly.
CAD CAD users users competently competently produce produce 2D drawings 2D drawings & & 3D 3D models models for for manufacturing manufacturing of of materials. materials.
3D 3D CAD CAD revolutionized revolutionized manufacturing manufacturing sector sector over over past past years years for for designing complex designing complex products products faster. faster.
Who use CAD? Manufacturers work with CAD to meet aerospace & automotive manufacturing
CAD is used in industrial market for making quality productsfaster
Engineers from industrial & manufacturing to civil engineering & plant design use CAD programs
2D drawing formats include DXF & AutoCAD DWG, while 3D formats include SolidWorks, Creo, IGES, STEP & SAT
What is BIM?
BIM is a new technique through which architects, engineers & BIM helps to analyze contractors & visualize design at collaborate to pre-construction design & build a before the onset of commercial building construction process using same database & BIM model
BIM provides a digital representation of real facility, including mechanical, HVAC, structural, architectural, electrical and plumbing services
BIM enables resource sharing from inception to completion across design build stages.
BIM facilitates in creating a communication channel to push a project efficiently
Who use BIM? Architects Architects for for 3D Visualization 3D Visualization & & Design Design Development Development & & Coordination Coordination

What are the Benefits of BIM? BIM engineering provides a complete representation of building design, considering core components of building like electrical, HVAC services, space and resources. BIM pulls documents into single database, where project stakeholders work on same model, saving to cloud. This allows instant updates, without wasting time for documents while making modifications. BIM model allows prefabrication of components ahead of time. So, there is no need to make adjustment as per building design. BIM provides options to clients to update model constantly while working on project, checking any time, leading to quicker approval & efficient project development. BIM model helps resource tracking to figure out resource requirement during design stage, improving the flow & construction efficacy.
What are the Benefits of CAD? CAD provides all tools to create basic 2D & 3D models.
CAD includes a host of features. Advanced users use them for creating complex models.
CAD lets you spot errors for architects and engineers.
CAD creates documentation for complex projects and you can refer back as per requirement.
