的Revit API收集：无法投值：空格TARGET_TYPE：

Question

我不明白为什么我的代码，它正常工作与其他的Revit类别：

# -*- coding: utf-8 -*-
import rpw
from rpw import revit, db, ui, DB, UI

dd1 = rpw.db.Collector(of_category='Spaces') 

产生这个错误：

什么样的目标类型？如果你的目标类型的房间，说明由The Building Coder的Collecting all Rooms on a Given Level讨论提供：您不能直接收集Room元素，因为它们是API的Revit的人工构建，不Revit中的原生里面存在。因此，你需要收集SpatialElement对象相反，Room父类，和后处理的结果，例如，将它们转换成客房。参见Accessing Room Data和Filtering for a Non-Native Class。
