  1. Draw the rooms.

    Drag a rectangle on the metric plan, or add a room by dimensions in Floor settings. Edit its polygon points for other shapes. Rooms define floor areas only.

  2. Give them walls.

    Select a room and choose Build wall outline, or draw individual wall segments. Exact shared walls are reused. Walls stay separate when rooms move.

  3. Open up the space.

    Choose Add door or Add window, then click a wall. Adjust width, distance from wall start, sill, and head in the inspector. These are actual holes in the 3D walls.

  4. Make it your own.

    Open the Item library, choose a design, and click inside a room to place it. Change its finish and color in Item details, inspect the 3D preview, and export JSON when ready. Entity IDs are optional; leave them blank for a drawing.

FROM DRAWING TO HOME ASSISTANT

Export, build, and install your plan.
