I have a spiral shaped cut around a cylinder, where I want to remove the strip that is in the spiral shape. I am trying to do this programmatically with python, but I’m not so sure where to begin with the methods for splitting/trimming objects from the brep class. I think this application is a little more tricky too, since I am splitting a cylinder the seam breaks up the cut so the result is more than just piece A and piece B.
The file below shows the objects I start with, and the desired goal that I would like to automate into a routine. In summary, it’s using a closed curve to split a brep surface which is periodic, and the closed curve goes across the surface seam multiple times.

Any general practices for splitting or adding trim curves to a brep would be really helpful, as I couldn’t find much in the McNeel Python Examples.
Below is the intended result; here I have manually picked the surfaces to get rid of.
