Round four of Rogue Olympics had the theme word "Draft," which called to mind drafting tables, which dominated architecture and engineering design work until they were supplanted by CAD. While I mostly stick to physical building, I had limited access to my bricks, and I saw a bitter irony in presenting a drafting table in CAD (Bricklink Studio). Fortunately, RO allows for digital entries!
