Autodesk's BIM software
Autodesk Revit is a building information modelling software for architects, landscape architects, structural engineers, mechanical, electrical, and plumbing (MEP) engineers, designers and contractors. It can be used as a very powerful collaboration tool between different disciplines in the building design sphere.
With this software, users can design buildings, structures, and their components in 3D, while also annotating the model with 2D drafting elements, and accessing the building information directly from the building model's database. The 4D building information modeling facilitated with Revit offers a variety of tools to plan and track different stages of the building's life-cycle, from conception to demolition.
