> Hi all - thanks a lot for the effort - I’ll try to get that running (on the road and busy…) - but so I tryed to retype the code and and it stll does not want to work for me… import clr clr.AddReference(‘ProtoGeometry’) from Autodesk.DesignScript.Geometry import \* Import ToDSType(bool) extension method clr.AddReference(“RevitNodes”) import Revit clr.ImportExtensions(Revit.Elements) Import DocumentManager and TransactionManager clr.AddReference(“RevitServices”) import RevitServices from R…

Thanks to @Kulkul😉
