What are the advantages of AutoCAD over Revit, and vice versa?

AUTOCAD is a basic drafting tool which was earlier designed to draft fast & accurate drawings at the schematic stages. Later if you go indepth with the details such as heights, structure, material calculation, quantities and automatic formation of schedule of openings with respect to the change in floor plans, these kind of advanced options are available in revit but for intial stages i prefer autocad as a good tool to present your ideas which can later exported to revit & develop the project accordingly. read less

Revit is a BIM tool. That is building information modeling. So here are some features you don't find in a CAD tool like autocad. 1- parametric components: every single element is no longer a2d entity. Each element is a3d object with parameters that can be modified to modify the entity 2- bidirectional assosiativity: the entire model is a single database with all elements interrelated. The significance of this is that when you make any changes in one location all affected elements will dynamically update. The2 above mean that by creating2d plans you are automatically generating3d models. In other words all you have to do is request Revit for a section and you're done. This is the same for elevations, callouts, and as you might imagine takeoff. So with simple yet intuitive tools Revit will provide you with a schedule based on the category of your choice extracting data from the elements. 3- documentation is no longer manual. The information is already there. All you have to do is extract it. This can be done using tags or keynotes. Tags simply extract the information from the elements themselves. Keynotes link your elements to the specification file. So the contractor knows exactly where to look for the information in the project specs. 4- worksharing: this means that you can work on the same project and synchronize information to a central file located on the server while everyone is separately working on their own computers. Since2013 you no longer need to be out the same server or even the same country. This is all adhered to the power of cloud computing. The above form less than10 percent of the features: others include but are not limited to the following:Point clouds, structural analysis, energy analysis, solar studies, daylight analysis, pipe and duct calculations, fill legends, and many more. ‎ read less
