Hello,

i tried to find some stuff, but it never matches with my collecter. so how do i get Elements from linked files f.e. walls ?

```auto
import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import List

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument
linkedDoc = FilteredElementCollector(doc).OfClass(RevitLinkInstance)

elelist = UnwrapElement(linkedDoc)

outlist=[]

for ele in elelist:
		type_id = ele.GetTypeId()
		ele_type = doc.GetElement(type_id)
		ele_fam = ele_type.Family
		ele_name = ele_fam.Name
		outlist.append(ele_name)

OUT = outlist

```

Have you tried:

```auto
linkedDoc = FilteredElementCollector(doc).OfClass(RevitLinkInstance).ToElements()

```

Hi,  
an example

```auto

import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import List

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

lst_rvt_link_inst = FilteredElementCollector(doc).OfClass(RevitLinkInstance)

outlist=[]
for inst in lst_rvt_link_inst:
	if RevitLinkType.IsLoaded(doc, inst.GetTypeId()):
		lnkdoc = inst.GetLinkDocument()
		elelist = FilteredElementCollector(lnkdoc).OfClass(FamilyInstance)
		for ele in elelist:
			type_id = ele.GetTypeId()
			ele_type = lnkdoc.GetElement(type_id)
			ele_fam = ele_type.Family
			ele_name = ele_fam.Name
			outlist.append(ele_name)

OUT = outlist

```

@Draxl_Andreas I know it got solved, but what would happen if you use `.FamilyName` as the property instead of `.Family` as it doesn’t exist for `RevitLinkType` in your old code:

@leonard.moelders ,

i modived it a little to my disieres…

```auto
import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import List

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

lst_rvt_link_inst = FilteredElementCollector(doc).OfClass(RevitLinkInstance)

walls=[]
outlist = []

for inst in lst_rvt_link_inst:
	if RevitLinkType.IsLoaded(doc, inst.GetTypeId()):
		lnkdoc = inst.GetLinkDocument()
		elelist = FilteredElementCollector(lnkdoc).OfCategory(BuiltInCategory.OST_Walls)
		for e in elelist:
			outlist.append(e)

OUT = outlist

```

@Draxl_Andreas I meant more like this:

```auto
import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import List

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument
linkedDoc = FilteredElementCollector(doc).OfClass(RevitLinkInstance)

elelist = UnwrapElement(linkedDoc)

outlist=[]

for ele in elelist:
		type_id = ele.GetTypeId()
		ele_type = doc.GetElement(type_id)
		ele_famname = ele_type.FamilyName
		outlist.append(ele_famname)

OUT = outlist

```
