Create and reshape rooms with exact dimensions

Create the room shell before placing cabinets or furniture. Room Planner stores dimensions in centimetres and uses the same measured outline for the 2D plan, 3D walls, floor area, openings, placement checks, and material estimates.

Choose a starting shape#

From Build → Room, choose one of these paths:

• Draw room creates a custom polygon point by point.
• 4 × 4 room creates a 400 × 400 cm room.
• 3 × 4 room creates a 400 × 300 cm room in its placed orientation.
• L 6 × 4 room creates a 600 × 400 cm L-shaped envelope.
• Create a room from photos opens Room Vision when that feature is available.

The presets include practical starter openings. They are starting points, not fixed templates; you can move, resize, replace, or delete their doors and windows.

Draw a custom outline#

1. Select Draw room. Room Planner switches to the 2D Plan view.
2. Tap or click each corner in order. Drawing uses a 10 cm grid and offers 45-degree direction and existing-point alignment assistance.
3. Select an on-canvas segment number if you already know its exact length.
4. Close the outline at the first point or use Finish when the shape is valid.
5. Use Delete point to remove the last point or Cancel to discard the unfinished outline.

A valid room needs at least three sides, cannot cross itself, and cannot contain a wall segment shorter than 10 cm. Draw the outer perimeter only; use interior walls for partitions.

Enter exact wall lengths#

In Build → Plan, select a wall or its dimension label, enter the centimetre value, and commit it. Room Planner moves the appropriate endpoint or parallel edge while trying to preserve the rest of the outline. The preview turns invalid when the change would cross another wall, collapse the room, detach required geometry, or make placed content impossible to keep.

For a rectangular room, command search can also create a rectangle when both requested sides are between 150 and 1,000 cm. This bound is for that command-created rectangle; an individual drawn wall follows the live geometry validator.

Move corners and whole edges#

Drag a corner to change the two adjacent walls. Drag an edge to move it parallel to itself. Helpful snaps keep aligned walls and joined partitions together. Openings hosted by a moved wall follow that wall when they remain valid. Interior walls, wall-mounted furniture, or adjacent room geometry can block a move rather than silently detach.

After a reshape, inspect all openings, wall furniture, floor furniture, finish areas, and dimension chains. A successful outline edit does not replace a real site survey.

Set the ceiling height#

The default ceiling is 280 cm. Set Ceiling height from 200–400 cm. Lowering it can invalidate a tall opening, wall-mounted item, marked space, or ceiling light position, so inspect the room after a large change.

Replacing or deleting a room#

Choosing a different preset replaces the current room shell and its contents as one history action. Deleting a room removes the room and everything inside it, including cabinets, furniture, doors, and windows, and requires a separate confirmation. Save a named Library version before either operation. Use Undo immediately if a replacement was accidental.

Add internal divisions with Interior walls and partitions, then add doors and windows.
