How to extract & merge 2 or more grasshopper assemblies

This a North American stud wall and while still in grasshopper I would like to trim out the stud wall for the doors and or windows framing. Still a novice at this

There is no one “right way” to do this. The two white groups create a “Union” Bounding Box (BBox) around the parts of the assemblies (up to the top of the headers) that need to be removed from the stud wall using Solid Difference (SDiff).
