Reactor Help Needed / Program Request

[sublimation]

I am struggling to put all the pieces together when it comes to using reactors and I was wondering if someone could write me a "simple" (in the sense of being minimal) program that I can study and expand to my fit my needs.  In the drawing I've attached, I would need to COPY, MOVE, DELETE, and UNDO any geometry I bring into the staging area.  However, the only thing important to me to understanding this is applying those reactors to the threaded hole marked E and propagating them to Plates A & B. 

 

I apologize if I am forgetting any needed information and would greatly appreciate any help you can provide.
