Autodesk ® Revit, Autodesk® Revit® Architecture, Autodesk® Revit® Structure and Autodesk® Revit® MEP

Autodesk Revit provides a rich and powerful .NET API which can be used to automate repetitive tasks, extend the core functionality of Revit in simulation, conceptual design, construction and building management, and much more. Revit .NET API allows you to program with any .NET compliant language including VB.NET, C#, and managed C++. The Software Development Toolkit (SDK) provides extensive .NET code samples and documentation to help you get started developing with the Revit API for Autodesk Revit Architecture/MEP/Structure.
