问题描述
我正在尝试使用带有空闲事件处理程序的Revit API在Revit 2017中自动执行pdf打印过程.我正在使用OpenDocumentFile方法打开revit文档，而不在任何地方使用ActiveUIDocument.此过程正在生成无效的操作异常.我不确定为什么会给出异常或是否允许使用Revit API.请帮忙.谢谢.
I am trying to automate the process of pdf printing in Revit 2017 using Revit API with Idling event handler. I am opening the revit document using OpenDocumentFile method and not using ActiveUIDocument anywhere. This process is generating Invalid Operation Exception. I am not sure why is it giving the exception or whether it is allowed using Revit API. Please help. Thanks.

推荐答案
除了IsPrintable字段外，您还需要检查的另一件事是视图是否实际上是视图模板.使用IsTemplate进行检查.
In addition to the IsPrintable field, the other thing you'll need to check for is whether the View is actually a View Template. Use IsTemplate to check that.
