For the presentation of one of our works, we should add a color legend indicating building functions. Many times, i tried to do this using Revit Mass models or Generic models (of course modelling one by one) but with dynamo, now we can construct a workflow for this job of course with less time. This is the result; 🙂 How i made it? If you have an office standard for color fill you can create two list for colors and departments. It will take less time then doing it manually. Thanks Mehmet from Red Hot Bim blog for his helps.
