#Converting input from Dynamo to Revit
line = UnwrapElement(IN[0]).GeometryCurve

ref = ReferenceArray()
ref.Append(line.GetEndPointReference(0))
ref.Append(line.GetEndPointReference(1))

#Create the dimension in a transaction
TransactionManager.Instance.EnsureInTransaction(doc)

dim = doc.Create.NewDimension(doc.ActiveView, line, ref)

TransactionManager.Instance.TransactionTaskDone()

OUT = dim
