The imputs to this node will be stored as a list in the IN variable.
doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
app = uiapp.Application
#doc = IN[0]
#duct = Autodesk.Revit.Creation.Document
#create workset collector
Ducttype = IN[3]
#extract workset’s name and ids
kk = IN[1]
ll = IN[2]
outs1 =
for m,n in zip(kk,ll):
xx= m.ToXyz()
yy= n.ToXyz()
TransactionManager.Instance.EnsureInTransaction(doc)
nwd1 = doc.Create.NewDuct(xx, yy, Ducttype);
outs1.append(nwd1)
OUT = outs1
TransactionManager.Instance.TransactionTaskDone()
