Slotted Door geometry and initial designs are done, very happy with these. As of this posting, I'm only showing the "Arched" doorways and doors, there are also a "Square" (Rectangle) standard doorway set as well. As with the other features of the system, I wanted variation. Wooden doors, reinforced doors, iron doors, portcullis, hidden, magical and coffee making. I'll add additional images when able. Enjoy!
