Answer : Autodesk Revit is a building information modeling software application for architects, engineers, and construction professionals. It allows users to create 3D parametric models of buildings.
Autodesk AutoCAD is a computer-aided design (CAD) and drafting software application used to create 2D engineering drawings and 3D models. It allows users to construct, edit, view, translate, and print drawings made with AutoCAD components.
From the descriptions provided, it seems that Revit may be harder to use than AutoCAD. However, this depends on the individual's level of experience with each program.
