#The inputs to this node will be stored as a list in the IN variables.
dataEnteringNode = IN

elementA = UnwrapElement(IN[0])
elementB = UnwrapElement(IN[1])

doc = DocumentManager.Instance.CurrentDBDocument

results = []

#Unjoin
TransactionManager.Instance.EnsureInTransaction(doc)
for A in elementA:
for B in elementB:
try:
result = Autodesk.Revit.DB.JoinGeometryUtils.UnjoinGeometry(doc,A,B)
result.append(result)
except:
pass
TransactionManager.Instance.TransactionTaskDone()

#Join
TransactionManager.Instance.EnsureInTransaction(doc)
for A in elementA:

result.append(result)

#Switch Join
TransactionManager.Instance.EnsureInTransaction(doc)
for A in elementA:
for B in elementB:
try:
result = Autodesk.Revit.DB.JoinGeometryUtils.SwitchJoinOrder(doc,A,B)
result.append(result)
except:

OUT = results

You need to instal the Hotgear package
it has a lot of nodes for join etc

Auto Join without Order.dyn Please do not work

the nodes from hotgear are working

I didn’t find These fields

Modify it to achieve this
I’m sorry to waste your time

it depends on the way you use it probably. one time run goes great. two times not. thare for you need to restart dynamo.
But now i put a toggle from the Rhythm package. you can run it as much as you like.

I’m still sorry the problem
Once again Thank you

in my case it works
i put all 3 options in one script
you have to run one option and delete or freeze the other 2

have Revit 2018 and Dynamo version 1.3.2.2480

What version off Dynamo do you use?

my version Revit 2017 and Dynamo version 1.3.2.2480

Works only SwitchJoin.Geometry For one column
