Subtracting two Surfaces to find difference

Hello everyone!

I am struggling with the following problem. I have a list of two breps (that I converted to poly curves also). I want to subtract the larger brep from the smaller breps and find the remaining surface (difference). I have tried to match the data also but it’s somehow failing for me. Could you please look into this problem and provide some insight?

Thanks a lot!

The picture shows the areas/surfaces which I would like to have after subtraction (not only at the top level but at all levels).
