Previously only available for German customers, the new Roombook Extension with International and German standards has been made available for Subscription customers on the Subscription Center.
"The Roombook Extension 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."
In essence this extension allows you to quantify materials beyond what is possible in the core Revit product, for example applying height reductions for specific materials and manually applying materials to sub-areas.
