Slicing a wall

Is there a way/tool to simply slice (divide) an object such as a wall? I often find myself wishing so because when I’m creating architecture I’m often creating on the fly. For example, if I have a rectangle that I’ve grouped, created 6" thick walls via FollowMe, and pulled them up to 8’, but at some point realize I want to protrude or extrude a wall. No can do without jumping through hoops?

Could you show us an example of what you are trying to do? Give us a visual. I expect it’s easier than the way you have been doing it.

try plugin call " zorro " or use the section plane for cutting part.
