Drop a prebuilt room

The Prebuilt Room tool drops a rectangular room of typed dimensions onto the canvas in one step. Use it when you know the room is a clean rectangle — most bathrooms, bedrooms, and small reno scopes — and you don't want to chain four wall draws to get there.

Steps

1. Click the Prebuilt Room icon in the left toolbar, or press R. The icon is a small closed square.
2. The Prebuilt Room dialog opens immediately. The dialog does not ask you to click first — the room places at the centre of your current viewport.
3. Type the Width (horizontal) — for example, 10' or 120 (imperial), or 3m or 3000 (metric).
4. Type the Height (vertical) — same format.
5. Click Create.

The room appears centred on the viewport with four walls connected at the corners.

Accepted input

The dialog accepts the same formats as the Length field (Value Command Bar) with one difference: a bare number with no unit marker is treated as feet in imperial (because residential rooms are almost always spec'd in feet, not inches). So 10 in imperial means 10 feet, not 10 inches. Explicit markers (', ", m, cm, mm) override the default.

Input	Meaning
10 (imperial)	10 feet
10'	10 feet
10' 6"	10 feet 6 inches
120"	120 inches
3m (metric)	3 metres
3000 (metric)	3000 mm

Size limits

The dialog rejects values larger than 100 feet (30,480 mm) per side. If you type a too-large number, a snackbar appears with Room too large — max 100' per side. Check your input. Most accidental rejections are a missed apostrophe — 300 in imperial would be 300 feet, not 30.

Tips

• The room places at the centre of your current viewport, not at the canvas origin. Pan to the area where you want the room before activating the tool — see Pan, zoom, and centre the canvas.
• Need a non-rectangular room? Use the Draw Wall tool — see Draw a wall. The Prebuilt Room tool only produces rectangles in v1.
• Each prebuilt room lands in the same room as your other walls — it doesn't create a separate project room. To split rooms inside one project, use the room tabs below the app bar.
• Cancel the dialog with Cancel or the close button if you change your mind. No room is created until you press Create.
