I thought the native OBJ exporter came with Pro only Please explain... There is my clunkier OBJexporter Ruby, BUT that [unlike the Pro version] doesn't have the option to NOT triangulate faces. You need to deal with the triangulation in the receiving app... Can you try another format like DAE ?

@razer said: Hey guys Im trying to find a plugin that will let me Snap my components together by edge face or vertex, Using shift+alt is a pain snapping to wrong faces and stuff. Thanks Don't forget the move tools capability to move to absolute or relative coordinates based on key board inputs. I use it most often for moving to origin by inputting [0,0,0]

Thanks Kwok. It's exactly what I wanted.

Why not draw the lines across the top as you show in your second image and then use Push/Pull to push the angled portion down to eliminate it? That will leave you with the faces on the ends of the remaining walls. You could also draw the cut lines on the bottom of the walls and simply erase the edges in between. No plugin needed for either method.
