Start with Quick Room or manual walls

Quick Room is best for a rectangular room. Manual drawing is best for L-shapes, extensions, open-plan spaces and irregular outlines.

  1. 1

    Quick Room

    Enter width and depth, then use each side of the room to add doors or windows. Enter an opening width and choose centred or a custom offset.

  2. 2

    Manual walls

    Select Draw Walls or press W. Click to place a start point, click again for the next corner and continue. Double-click, press Escape or reconnect to the starting point to finish.

  3. 3

    Create more than one enclosed space

    Continue drawing internal walls. Each fully enclosed area is detected as a room and included in the plan overview.

Enter exact wall dimensions

  1. 1

    Select the wall

    Open the wall controls and type the exact length and thickness instead of relying on dragging.

  2. 2

    Choose the wall type

    Mark a wall as interior or exterior so the plan and 3D view use the appropriate wall treatment.

  3. 3

    Choose what is measured

    Use inside faces when your measurement is the usable room size. Use full wall when your measurement includes the wall thickness.

  4. 4

    Move connected walls

    When a wall moves, connected corners stay joined. Detach it first when you need to move that wall independently.

Control units and measurements

  • Switch between metres, centimetres, millimetres, and feet and inches from the units control.
  • Show or hide all measurements when the plan becomes busy.
  • Use the plan overview to check total floor area, total wall length and object counts.

What Snap does

Snap is one switch with several jobs. With it on, the things you move are pulled onto the places that make a tidy plan. With it off, everything moves freely and lands exactly where you let go.

  • Grid: wall ends and items settle on the grid, 1 cm in metric or 1 inch in feet and inches.
  • Wall joins: a wall end you draw or drag is pulled onto nearby wall ends, wall faces and tape-measure guides, so rooms close cleanly.
  • Room corners: when you drag a corner, dashed guides show where both walls would run straight and a target marks the exact 90° point. The corner lands only on that point, and the corner readout turns green and says 90° when it does. Anywhere else the readout shows the true angle, such as 89.6°.
  • Items: furniture and fittings pull onto walls, line up with neighbours, and a square item dragged into a corner settles against both walls.
  • Snap off: corners, walls and items move freely. The angle readout still shows the true angle, so you can see when a corner is a fraction off square.
  • Hold Alt while dragging to flip Snap for that one move. Hold Shift while dragging a corner to lock it to one axis.

Add doors and windows

  1. 1

    Open Structure

    Find doors, double doors and windows in the Structure section or search for the item by name.

  2. 2

    Place the opening on a wall

    Drag or tap the item, then move it to the correct wall. Wall snapping helps it align with the wall.

  3. 3

    Set its size and direction

    Enter the exact width, rotate or mirror the item where supported, and check the door swing on the plan and in 3D.

Questions about this guide

Common questions

How do I enter exact room dimensions?

Select a wall and enter its exact length and thickness. For a rectangle, Quick Room lets you enter the room width and depth before it draws the walls.

Read Draw and measure a room
What is the difference between inside and full-wall measurements?

Inside measurements describe the usable space between the inner wall faces. Full-wall measurements include wall thickness. Choose the option that matches how you measured the real room.

How do I add a door or window?

Find the item under Structure or search for it, place it against the correct wall, then set its width and direction. Quick Room can also add openings while creating a rectangular room.

Why do other walls move when I move one wall?

Connected corners stay joined so the room does not accidentally break apart. Detach the wall first when you need to move it independently.

What does Snap do, and why do room corners only lock at 90°?

Snap has several jobs: it settles wall ends and items on the grid, pulls wall ends onto nearby walls and guides, aligns items with walls and neighbours, and lands a dragged room corner on the one point where both walls run straight. That point is the only true 90°, so the corner locks there and nowhere else; dashed guides and a target show it while you drag, and the readout turns green and says 90° when you reach it. With Snap off, corners move freely and the readout shows the exact angle.

How do I stop walls or furniture snapping?

Turn Snap off from the toolbar, or hold Alt while dragging to override it for one move. With Snap off, walls, room corners and items go exactly where you let go and the corner readout shows the true angle. Turn it back on for clean wall joins, true 90° corners and tidy alignment.

Read Position items precisely
Can I draw an L-shaped or irregular room?

Yes. Use the Wall tool instead of Quick Room and place each corner manually. Join the final wall to the first so the planner detects the enclosed area.
