Hello, thanks for reading this... When I draw 2 different wall types ("Wall A" and "Wall B"), the core of Wall A wants to cut right in to the core of Wall B and make the join in there, instead of simply butt-joining at the outside of Wall B (which is what I'm aiming for). It may have something to do with the end of the wall wanting to snap to the gridlines that are in place? What's the best way to deal with this?
