Hi,
try the python code below. Input is a list of rooms. Output is bounding elements, regardless if they are from current or linked doc.
import clr
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument
#The inputs to this node will be stored as a list in the IN variables.
rooms = UnwrapElement(IN[0])
options = SpatialElementBoundaryOptions()
options.SpatialElementBoundaryLocation = SpatialElementBoundaryLocation.Finish
output = []
for r in rooms:
segments = r.GetBoundarySegments(options)
boundaries = []
for sl in segments:
for s in sl:
#boundaries.append([s.ElementId,s.LinkElementId])
e = doc.GetElement(s.ElementId)
if isinstance(e,RevitLinkInstance):
linkDoc = e.GetLinkDocument()
linkElement = linkDoc.GetElement(s.LinkElementId)
boundaries.append(linkElement)
else:
boundaries.append(e)
output.append(boundaries)
#Assign your output to the OUT variable.
OUT = output
