ElumTools is the first (and only) fully integrated lighting calculation add-in for Autodesk® Revit®. ElumTools is designed to calculate point-by-point illuminance on any workplane or surface utilizing lighting fixture families and surface geometry already present in the Revit model. ElumTools runs completely inside of Revit with its own ribbon toolbar to provide quick access to analysis tools for Revit Rooms, Spaces, Regions and Views.
