To draw a simple house, activate Draw Mode and enable Auto Generate for walls, floor, ceiling, and roof. Use the Line Tool or Room Tool to create a closed shape—commonly an L-shaped layout. As the shape is completed, the app automatically creates the structural elements. Measurements display on each edge, and the structure becomes visible in 3D view. Use Select Mode to refine wall positions or roof styles. This approach allows rapid concept modeling, and additional rooms can be added by repeating the process or extending existing geometry. Drawing a basic house typically takes less than a minute, ideal for fast iteration and early design discussions.
