Five starters, each drawn as a real floor plan: a 30×40 cabin (2 bed / 1 bath), a 40×50 split plan (3 bed / 2 bath), a 40×60 shouse with a 20′ shop, a 40×60 open plan (4 bed / 2½ bath) and a 50×80 shouse with a 30′ shop. Use this copies one into the building — ⌘Z puts back what you had, and editing the building never changes the starter. Each one comes with escape windows in the bedrooms, a working kitchen, baths, laundry and the electrical already placed.

When a layout sells, Save this building as a template. It shows up under Your templates for everyone on the account, right next to the starters. Remove takes one off the list — and buildings already made from it are not touched.

The building has a Post frame / Barndominium switch in the header. Barndominium adds the Floor plan button. Switch back to Post frame and the plan is hidden, not deleted — "The floor plan is kept — switch back to Barndominium to see it." Nothing is lost on a mis-click.

Press Floor plan and the camera flies straight down, the roof disappears and a drafting sheet opens over the shell you already drew in the 3D designer — the posts, the girts and every window and door from the 3D model, sitting in the plan's outside walls. Tools down the left, most common first. On the right: 1,432 sq ft living, 727 sq ft shop, 2,400 sq ft footprint, with the code check under it.

Back in the 3D view, the roof stays off and the rooms stand up like a dollhouse — interior walls, the kitchen run, the shower, the shop and its overhead door. Walk takes you through the rooms at eye height.

Pick Room box, choose what it is — Bedroom, bath, closet, office — and drag. The live size reads 12′-0″ × 13′-0″ as you go; let go and the walls are drawn and the room is named. A box drawn against another shares the wall, and an edge on the outside wall draws nothing, because the shell is already there.

With Wall, click to start and type the length — 12' 6 1/2", 150.5 or even 3.81m — then press Enter. Walls snap to ends, to other walls and to 45°, and the Snap step runs from 1/16″ to 1′. Pick the build first: a Plumbing wall is 2x6 and draws 6½″ thick, because a 3″ drain doesn't fit a 2x4.

Click a wall to drop a door — swing, pocket, bifold, barn slider, double or cased opening, in the sizes you order (2868, 3068…). Select one to Flip hinge or Flip swing, set its height, and mark it Fire-rated and Self-closing. The panel shows the clear width (33.5″), the rough opening (38.0″ × 82.5″) and the two rooms it joins — here, Shop · Mudroom.

Kitchen & bath opens the library: base, wall and tall cabinets, vanities, islands, plumbing fixtures and appliances. Pick one and click near a wall — it snaps to the wall and faces the room. Cabinets carry their order codes on the plan (SB36, B24, W3615), and the countertop is drawn over the base run.

Select a room and press Place code-minimum electrical. It adds the receptacles NEC 210.52 asks for along the walls, a switched ceiling light, and the smoke alarm a bedroom needs under IRC R314. Bedroom 1 goes from four Fix items to nothing flagged. Select a switch and tick the lights it turns on; the switch legs print on the electrical sheet. It's design intent for your electrician.

The right-hand panel checks the plan as you draw against IRC 2021 or IRC 2024 and NEC 2023. Each item is a Fix (fails as drawn), a Check (probably fails, or depends on something the plan can't see) or a Note, with the section number, a one-line fix and a marker on the plan. Pick IRC 2024 and the numbers follow the edition — R314.3 becomes R310.3. It's a builder's checklist with section numbers; your county's plan review still decides. The shell gets its own buildability check for what won't frame.

Turn on Clearances and every fixture shows the clear floor it needs as a dashed zone. Slide a toilet too close to the vanity wall and the check says exactly why: it needs 15″ from its centre to the side and 21″ clear in front.

Five switches along the top of the drawing: Dims, Electrical, Code, Clearances and Grid. Turn electrical off to talk layout with the customer; turn dims and code back on to check it yourself.

Dimension measures between any two points — snapped to wall ends and wall faces — and the line stays on the plan. Here it checks the primary bedroom corner to corner: 18′-1 7/8″. Every outside wall already carries its dimension strings: the overall length, then the window and door positions. Lengths print to 1/16″.

Takeoff counts the inside of the building from what you drew — framing, insulation, drywall, doors & trim, flooring, tile, cabinets & tops, paint, electrical, plumbing and appliances: 140 lines on the Ostrander plan, from 160 precut 2x4 studs for the interior walls to 52 sheets of ½″ drywall. Every line says how it was counted, and Download CSV hands the list to your supplier or spreadsheet. The shell has its own material takeoff.

Print sheets makes five 11×17 sheets with a title block: A1 floor plan, A2 electrical with switch legs, A3 schedules (doors, windows, rooms & finishes, cabinets, fixtures), A4 notes and the code check, A5 the takeoff. The plans print at a true scale — ⅛″ = 1′-0″ for this 40×60 — with a scale bar, so a tape on the paper reads a real measurement. Every sheet says what it is: design intent, not an engineered or sealed drawing.
