How to receive Pipes in doc

Revit

Hi all,

How can I receive the pipes that are in my document?


import Autodesk #Loads the Autodesk namespace
import Autodesk.Revit.DB as RDB #Loading Revit's API UI classes module kan nu worden aangeroepen met RDB.xxxx
#from Autodesk.Revit.DB import * #Loading Revit's API UI classes
import Autodesk.Revit.UI as RUI # Loading Revit's API UI classes als RUI.xxxx
#from Autodesk.Revit.UI import * #Loading Revit's API UI classes

doc = DocumentManager.Instance.CurrentDBDocument #Dit is het actieve Revit document
uiapp = DocumentManager.Instance.CurrentUIApplication #Een handle instellen voor het actieve Revit UI-document
app = uiapp.Application  #Een handle instellen op de momenteel geopende instantie van de Revit-toepassing
uidoc = uiapp.ActiveUIDocument #Een handle instellen op de momenteel geopende instantie van de Revit UI-toepassing
revit_version = int(doc.Application.VersionNumber)
# code omrekenen revit feet naar huidig ingestele document units
if revit_version >= 2022:
    ForgeLength = "autodesk.spec.aec:length-1.0.0"  # zie voor lijst ForgeTypeIds.xlsx in de map handleidingen
    ForgeTypeLength = RDB.ForgeTypeId(ForgeLength)
    getDocUnits = doc.GetUnits()
    getDisplayUnitsLength = getDocUnits.GetFormatOptions(ForgeTypeLength).GetUnitTypeId()
else:
    getDocUnits = doc.GetUnits()
    getDisplayUnits = getDocUnits.GetFormatOptions(RDB.UnitType.UT_Length).DisplayUnits


def ToRevitUnitsLength(InVal):
    if revit_version >= 2022:
        return RDB.UnitUtils.ConvertToInternalUnits(InVal, getDisplayUnitsLength)
    else:
        return RDB.UnitUtils.ConvertToInternalUnits(InVal, getDisplayUnits)


def ToDynamoUnitsLength(InVal):
    if revit_version >= 2022:
        return RDB.UnitUtils.ConvertFromInternalUnits(InVal, getDisplayUnitsLength)
    else:
        return RDB.UnitUtils.ConvertFromInternalUnits(InVal, getDisplayUnits)

def ToRevitUnitsLengthFromMM(InVal):
	if revit_version >= 2022:
		return RDB.UnitUtils.Convert(InVal, RDB.UnitTypeId.Millimeters, RDB.UnitTypeId.Feet)
	else:
		return RDB.UnitUtils.Convert(InVal, RDB.DisplayUnitType.DUT_MILLIMETERS, RDB.DisplayUnitType.DUT_DECIMAL_FEET)
	
def ToRevitUnitsLengthFromMM(InVal):
	if revit_version >= 2022:
		return RDB.UnitUtils.Convert(InVal, RDB.UnitTypeId.Millimeters, RDB.UnitTypeId.Feet)
	else:
		return RDB.UnitUtils.Convert(InVal, RDB.DisplayUnitType.DUT_MILLIMETERS, RDB.DisplayUnitType.DUT_DECIMAL_FEET)
	
def get_parameter_value_by_name(element, parameterName):
	return element.LookupParameter(parameterName).AsString()

	
#einde code omrekenen revit feet naar huidig ingestele document units

#alle elementen van OST category ophalen
alleElementen = RDB.FilteredElementCollector(doc)
alleElementen.OfCategory(RDB.BuiltInCategory.OST_PipeSegments)
alleElementen.WhereElementIsNotElementType()

#ID ophalen voor parameter
ID = alleElementen.ToElementIds()

ParameterNaam="bouwnummer"

param = list()

for MyE in alleElementen:
	try:
		param.append(get_parameter_value_by_name(MyE, ParameterNaam))
	except:
		param.append(None)
	

OUT= alleElementen.ToElements()

I can get the Pipe Segment but it give me alot of elements, I only want the pipes I drew.
The WhereElementIsNotElementType() doesnt work with PipeSegments

@jw.vanasselt BuiltInCategory.OST_PipeCurves you need curves not segments
