I show how to cut a solid with cut with half spaces using a solid and two planes, then how to mirror the plane by reversing the normal, and pick the top face by checking face normal against XYZ base Z. I also recreate floors from curve loops and copy parameter values between old and new floors, handling read only parameters. I reference key Revit API docs like BooleanOperationUtils cut with half spaces. There is no explicit action requested from viewers."}
