How to Get the Best Results

Start with Accurate Measurements

The entire design depends on accurate room dimensions. Measure walls, ceiling height, window positions, and door locations carefully. Even small errors compound when placing furniture.

Work in 2D First, Then Switch to 3D

Get the layout right in the top-down 2D view where proportions and spacing are clearest. Then switch to 3D to evaluate the visual feel, sightlines, and material combinations.

Test Natural Light

If the tool supports time-of-day lighting, check how your room looks at different times. North-facing rooms get cool light; south-facing rooms get warm light. This affects color choices significantly.
