What the 3D preview can show and what you need to enter first.
See your layout from another angle
The 2D plan is best for comparing positions and distances. The additional 3D preview helps assess heights and room boundaries. It visualises your inputs; it does not automatically survey the apartment.
Create rooms and walls deliberately
An imported PDF remains the reference. Draw rooms and building elements on top, then check their dimensions. Add doors, windows and ceiling heights based on the real apartment.
Enter furniture heights
Width and depth show the footprint; height reveals whether a wardrobe could meet a low ceiling. Replace library defaults with actual dimensions. Check the furniture's precise position under sloping ceilings.
Use the preview as a check
Switch between 2D and 3D, look from different directions and toggle labels as needed. Ceiling warnings depend on entered room and furniture heights and only cover what is in the model.
Confirm the decision on site
Use the preview to narrow down options and list questions. Re-measure critical spots before buying custom fittings or large furniture.
