Hello, I am a beginner of REVIT API.
Recently I have been writing a code that applies the filter rules in a short time.
Works well if only one filter rule is applied, such as the first capture.
However, the code for implementing a second capture, for example, does not work.
If a user-defined level exists, the user has created a code to add filter rules for it.
Is there a problem with my code?
thank you.
