When using CAD for designing buildings, you focus on creating 2D drawings. When using Bim (Building Information Modeling), you focus on creating models, and then the drawings could be generated from the models. Autodesk Revit is one of the most popular Building Information Modelling (BIM) solutions used by architects, engineers, and contractors. Revit moves beyond simple two-dimensional drawings and facilitates three-dimensional modeling and documentation of architectural structural and mechanical systems for a project‘s entire life cycle from the early stages of planning through construction. 1. Parametric Modeling The term "parametric modeling" refers to the process of creating 3D models from a set of rules. Revit employs parametric modeling via "families." Everything in Revit, from title blocks to 3D views to building components like walls or floors, is part of a "family"; some are integrated into the program, others are available through libraries, and some are created from scratch. A family may be built by assigning dimensions and properties to 2D or 3D data, which can subsequently be updated by a Revit user by modifying those parameters (for example, height, width, or thickness of a door family). This provides Revit models more flexibility over building design.

2. Automatism A single database contains all the data needed to build a Revit model. This implies that the database is updated anytime you make a modification to the model. The modifications are applied to the entire model, allowing automation and improving the efficiency of the building design process (as well as reducing some of the rework that results from "chasing" changes around our several project files). 3. Scheduling Similar to how a Revit model acts as a single database containing all of the model's data, scheduling in Revit reduces the amount of time required by conventional processes. One of the more time-consuming steps in the architectural design process may be streamlined if changes are made to the Revit model and immediately reflected in schedules that have been set up. Schedules may also be exported from Revit, changed, and then imported back in to assist with project management. 4. Collaboration The ability to allow several users to work in the same Revit model simultaneously, as opposed to AutoCAD, where only one person may make changes to a.dwg file at a time, is one of the more pronounced distinctions between Revit and AutoCAD. Users may submit their model modifications to a "Central" model using the "Sync with Central" tool in Revit, and they can also pull any changes made by colleagues to the same "Central" model into their "Local" copy of the model. The project team's full capacity for collaboration is enabled through this method. Collaboration across various teams and disciplines is further made easier by the vast plug-ins being developed by other software businesses and apps and the compatibility of Revit with other Autodesk programs like AutoCAD or FormIt. 5. Cloud-Based Access Remote work is increasingly the standard, if not the most, for many offices these days. The ability to access your Revit models at any time and from any location is provided by storing them in the cloud. Revit may be used with a variety of cloud-based systems. However, the most prominent is the BIM 360 platform offered by Autodesk. This platform functions as a "server in the cloud" where users may save their models, submit modifications to said models, mark up models and sheets, interact with team members, and even assist with facility maintenance after construction completion handoff — all through a web browser. This connectivity to the cloud expands Revit's capability and collaboration possibilities.

6. Coordinating Revit offers a wide range of practical capabilities for coordination across various models, file kinds, disciplines, and trades, whether it be as part of the architectural design process or when undertaking constructability evaluations from users in the construction sector. Users may transfer elements from a connected model into their base model using tools in Revit, keep track of changes made to a linked model, evaluate notifications of those changes, and report any issues to other teams working on the same project.

7. Presentation Rendering The design business has a long history of using many pieces of software for rendering and presentation materials. Nevertheless, Revit offers resources to produce these elements on a single platform. It saves a lot of time to be able to produce 3D drawings and renders directly in Revit rather than having to import your model into another piece of software, even if 3D modeling solutions like 3ds Max are very beneficial for particular industries, such as the animation sector. Utilizing its broad material libraries and rendering plug-ins, Revit offers capabilities for both 2D presentations and 3D visualization outputs. Additionally, various programs and plug-ins that work with Revit models may be used to examine and display your model in VR (vr technology) settings, enabling your team to collaborate from anywhere in real-time
