Architects widely use Revit for a number of reasons, but nowadays, it is gaining traction among civil engineers too. Civil Engineers widely adopt AUTOCAD to make plans for buildings, design for water tanks, and many more. Nowadays, this software is getting replaced by Revit as it offers 3D rendering quite quickly compared to AUTOCAD. Some additional blocks are also there in Revit that can be imported as plugins which are quite beneficial to place on the drawings without consuming much time.
Both AUTOCAD and Revit are the products of Autodesk, and they share many similarities despite having many differences. One of the main reasons Revit has become so popular is that it was built with the BIM process in mind, and it also works with cloud computing. This allows everyone participating in the project to get their hands on any information they need.
