Hi Dounia, i have got the same problem, what i did i restarted Revit and dynamo, it works in the end!
try to do that, other ways can you share the full graph ?
I’ve the following message : “DynaMapsNodesFunctions.CleanRevitExtrusionDS operation failed. The profile CurveLoops are open”.
I tried to randomly generate heights of extrusion cause the extract of the maps give me buildings with no height. But this solution doesn’t seem to work…
