Hello, I want to collect ducts at level 1, but I got empty result…what’s wrong with my code? [image] import clr import Revit clr.AddReference("RevitServices") import RevitServices from RevitServices.Persistence import DocumentManager clr.AddReference("RevitAPI") import Autodesk from Autodesk…

I think I know where is the mistake the builtin parameter of reference level of structural framing and duct is different :frowning: I changed BuiltInParameter.INSTANCE_REFERENCE_LEVEL_PARAM to BuiltInParameter.RBS_START_LEVEL_PARAM then I fixed the problem :slight_smile: [image]

@newshunhk , check out this topic [image] Get Element's LevelId Developers Unfortunately, there is not much documentation on this subject. I think that as CurveElements are workplane based this property return an ElementId.InvalidElementId (-1)

@newshunhk , you are looking for that ? [grafik] import clr # Import RevitAPI Classes clr.AddReference('RevitAPI') import Autodesk from Autodesk.Revit.DB import * # Import DocumentManager and TransactionManager clr.AddReference('RevitNodes') import Revit clr.ImportExtensions(Revit.GeometryConve…

no. I want to collect all ducts at Level 1 using python, I can collect all ducts, but I wanna filter the reference level “Level 1” as well. I tried to follow this blog and modify myself, but fail. https://thebuildingcoder.typepad.com/blog/2010/06/parameter-filter.html

@newshunhk try to create a second part levels = [GetPipesLevel(m) for m in pipes] OUT = [] for i in levels: OUT.append(i.BuiltInParameter.INSTANCE_REFERENCE_LEVEL_PARAM) #provider = ParameterValueProvider(ElementId(pips)) #rule = FilterStringRule(provider, evaluator, 'Level 1', False…

this is not what I want :frowning: sorry maybe my question is not clear… anyway thanks
