hello everyone.
why this node is not working on Beams & Columns faces? it works well with walls.
I’m trying to get the faces and the points that I picked to select the faces.
how do I get the faces & points of beams and columns?
There’s an issue with the code in that node when selecting columns and beams. Unfortunately, I don’t know enough about the error to provide input on the fix. Data-Shapes has a node called “Select Face (s) (PickObject)” that works.

Hi ,
here is a fix for structural Columns and Beams

import clr
clr.AddReference("RevitAPIUI")

clr.AddReference("RevitServices")
import RevitServices

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
clr.AddReference('RevitAPI')

def output1(x):
if len(x) == 1: return x[0]
else : return x
surfaces, gpoints = [], []
sel1 = uidoc.Selection
ot1 = Selection.ObjectType.Face
ref_list = sel1.PickObjects(ot1, "Select the faces and press Finish.")
for ref in ref_list:
el1 = doc.GetElement(ref.ElementId)
sf0 = el1.GetGeometryObjectFromReference(ref)
if isinstance(el1, FamilyInstance):
tf1 = el1.GetTotalTransform().ToCoordinateSystem()
else:
tf1 = Transform.Identity.ToCoordinateSystem()
sf1 = sf0.Convert(ref, tf1)
#
for i in sf1:
ref = i.Tags.LookupTag("RevitFaceReference")
# print(ref)
if ref is None:
i.Tags.AddTag("RevitFaceReference", ref)
surfaces.append(output1(sf1) )
gpoints.append(ref.GlobalPoint.ToPoint(True) )
OUT = output1(surfaces), output1(gpoints)

Thank you for the code, but it’s not working with column surfaces and points. It works perfectly with beams and walls as I wanted.
Please check again
Hi,
I have not been able to recreate this bug can you share your rvt file?
Here is a workaround by recomputing References with StableReference
I’ve only done a few tests, so it’s worth trying out on several objects and several versions of Revit.
