"Revit" means 'Revise Instantly'. Revit has gained great prominence in CAD and Engineering Industry and is gradually decreasing the use of AutoCAD. Though it is not possible to make AutoCAD extinct, Revit is efficient than AutoCAD in performing certain functions like construction documentation, synchronized planning, scheduling etc. Construction industry works on 2 principles-Precision and Turnaround time. Revit helps in fulfilling both the principles by providing precision and quick results.

Autodesk Revit not only helps you to construct 2D and 3D construction documents easily but it does much more than that. Revit helps in creating Intelligent Models. It is widely used for Building Information Modeling which allows the user to design high end buildings, infrastructure etc using parametric modeling and drafting elements. It brings together effective combination of plans, sections, elevations, schedules, etc.

It transforms thoughts of Architects and Designers into reality by using building design tools. On other hand it also captures the early design thinking to better support design, documentation and construction. Revit architecture not only visualizes and analyzes the materials, quantities, sun position and the solar effects thereby facilitating smarter and more sustainable design. It also permits a greater level of cooperation and communication and simultaneously greatly improves the ability to coordinate a team better.

One of the widely acclaimed features of Revit is the 'Building Maker feature'. It selects, adds, helps you transform your conceptual forms into fully functional designs.You can create walls, curtain systems, floors and roofs. So, it means that one click on the button and one's plan turns into a 3D building exactly with the desired specifications.

Revit supports parametric Systems, it's flexible embedded devices facilities help the user to make informed decisions along with synchronized planning, design and precise documentation. A successful implementation of BIM along with the better planning Project 4D and 5D technologies, energy analysis and cooperation with the project in various disciplines results in the exact quantities, the automatic changes before visualization, spatial recognition of possible conflicts prior to construction. No wonder, users believe that Revit offers clear benefits for all projects irrespective of the requirements' intricacies.

Of every construction project in the world, the owner spends 5% on design and 95% on construction. Surprising fact is that the success of the later depends on the former. Revit can identify the potential spatial conflicts and forecast the building performance at the early stages of design more efficiently than AutoCAD. In today's scenario, BIM process is seen as the main way for the CAD industry, and Revit works as the backbone of the BIM thought process.

Revit functions as intelligent software. Unlike AutoCAD, the parametric components carry information about their relationships to other objects in the building in contrast to the blocks and solids. AutoCAD dimensions only display the distance between two entities. But in case of Revit, when the dimension value is changed the objects associated to the dimension are moved.

ACCESS TO SINGLE FILE
In Revit, all project data is stored in the single environment (Revit project file) whereas in AutoCAD enables designers to store and retrieve project data from multiple files.

No Command Line or Layers
Revit has the Category Visibility features. Color and line type are also controlled by category features unlike AutoCAD's Freeze/Thaw/On/Off by view point feature.

Revit Family vs. AutoCAD Block
Revit stores similar parametric components with varied styles in family, allowing quick organization and data sharing whereas AutoCAD enables users to store symbols as blocks in individual DWG files.

Worksharing of Projects
Revit allows multiple users to work on the same project file and merge their changes with every save.

Multiple Design View
Autodesk Revit makes extensive use of various views of the parametric building model. Autodesk Revit allows the designer to work with components in any view, be it plan, elevation, section, perspective or from within a schedule.

Automated 2D Floor Planning Tools
Floor planning is the pivotal component in a construction document set. Revit's smart building components and 3D symbol expedite floor planning and schedules. A typical CAD program can't match the quality and speed of Revit's floor planning tools.

Automatic Sheet Set Management
Revit automatically scales dimensions, text, annotation tags, line types and hatch patterns based on the viewport's scale. As sections, elevations, details are placed on a sheet they are automatically numbered and their reference labels are updated in the plans, sections or elevations that reference them.

The above differences between AutoCAD and Revit Architecture would enable you to make a more informed decision.
