I use the follow code to create stairs in revit by dynamo.It seems work but not work well.I have met two problem.
1、It’s very strange that newStairsScope.IsPermitted 's value is false,I just open a new file and run my script,I think it don’t have the condition like“StairsEditScope is not permitted to start at this moment for one of the following reasons: The document is in read-only state, or the document is currently modifiable, or there already is a stairs edit mode active in the document. ”
2、It always show me the following dialog,how to avoid this.
I code is following:
