Roombook Extension for Autodesk Revit Architecture 2012 is available through the Autodesk Subscription Center

The Roombook Extension for Autodesk® Revit® Architecture software helps calculate the surface area of walls, floors and ceiling elements, room circumferences and the total number of furnishing elements within a project.

In addition to the automated detection of room areas and surfaces, this extension helps users configure these elements manually to local requirements, as well as achieve more accurate model take-offs. Quantified results can be exported to Microsoft® Excel® software and Autodesk® Quantity Takeoff (QTO) software.
