If you are new to ElumTools, there are three essential functions you must be familiar with to ensure success. The first is the process of managing your lighting fixture (luminaire) families using ElumTools Luminaire Manager. The second is accurately accounting for the reflectance or transmittance of the materials in your Revit project using the ElumTools Materials Mapping feature. Then finally, the third function is the assignment of calculation points to work planes or surfaces to quantify light levels. The subsequent calculation process then ties it all together for accurate results for lighting in Revit.
