revit-api - RevitPythonShell - IronPython.Runtime.UnboundNameException：未定义全局名称“doc”

问题描述

我在 RPS 中编写了我的第一个按钮，但似乎在启动时或单击按钮时未读取 init 文件。这是我在尝试遵循 youtube 上提供的教程时遇到的错误。

IronPython.Runtime.UnboundNameException: global name 'doc' is not defined

在我将 init 脚本中的导入复制并粘贴到我的按钮文件中之前，我也遇到了 Filtered Element Collector 的类似错误。

有没有人有任何问题或找到任何解决方案？

这是我的代码出错的部分：

import os
import csv
import rpw
from rpw.ui.forms import Console
from rpw.ui.forms import SelectFromList

desktop = os.path.join(os.path.join(os.environ['USERPROFILE']), 'Desktop')
filepath = os.path.join(desktop, 'RevisionClouds.csv')

cl = FilteredElementCollector(doc)
cl.OfCategory(BuiltInCategory.OST_RevisionClouds)
cl.WhereElementIsNotElementType()

我在 Revit 2019 中，RPS 运行 python 2.7.7

这是我的 init.py 文件。我已经向它添加了更多的导入，它可以与 RPS 及其控制台一起正常工作。但是当涉及到 pyRevit Button 表单时，当它已经在 init 脚本中定义时，它会在 doc 中出错。

解决方案

以我的经验，“init”文件仅适用于即时使用控制台。当您将脚本部署到按钮（也称为“固定命令”）时，您需要包含“init”文件中的所有预先定义。

这可以解释为什么doc当您从控制台运行脚本时工作正常，但在部署到功能区按钮时没有定义。

这也是 init 文件的第一行所指的内容：

# these commands get executed in the current scope
# of each new shell (but not for canned commands)

尝试将所有代码import行添加clr.AddReference到您部署的按钮文件中，看看会发生什么
