在发电机中创建风管（Revit）

Question

我已经从博客中复制了发电机脚本，以便在revit中创建风管，但它无法运行。 enter image description here

我有没有错过任何愚蠢的事情？

由于错过了依赖项导入，我遇到了类似的错误。我在尝试选择特定的DuctType时也遇到了错误，因此我将其留空并且Revit API为我们选择了第一个。我能够用类似的方法使它工作：

请参阅Dynamo文件：Dynamo Add Duct .dyn image

import clr

# Import RevitNodes
clr.AddReference("RevitNodes")
import Revit

#import Revit DB
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

#import Revit Creation where Create.Duct is
from Autodesk.Revit.Creation import *
clr.ImportExtensions(Revit.GeometryConversion)

# Import Revit elements
from Revit.Elements import *

# Import DocumentManager
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

import System

#The inputs to this node will be stored as a list in the IN variables.
doc = IN[0]
x = IN[1].ToXyz()
y = IN[2].ToXyz()
ductType = IN[3]
#ductTypeUnwrapped = UnwrapElement(ductType) #not working

# Start Transaction
TransactionManager.Instance.EnsureInTransaction(doc)
doc.Create.NewDuct(x, y, ductType); #if DuctType is null then Revit picks first type. 
# Stop Transaction
TransactionManager.Instance.TransactionTaskDone()

OUT = doc
