Should a floor plan be a flat 2D drawing or a 3D model? The honest answer is that you need both, at different moments. A 2D plan is the working document a trade reads; a 3D view helps a client picture the space and helps you check heights. This guide explains when to use each and how RoomPlot lets you move between them from the same plan.
What 2D and 3D each do well
A 2D floor plan is a top-down drawing: walls, openings, room areas and symbols, all to scale. It is precise, prints cleanly, and is the format builders, surveyors and councils expect. A 3D view shows the same space with height and depth, which is far easier for a non-technical client to read and useful for checking ceiling heights and sightlines.
When to use a 2D plan
- Trade and council documents where exact dimensions and standard symbols matter.
- Property listings that need a clean, labelled room-by-room layout.
- Zone plans for fire, security and CCTV work, where coverage and symbols read best from above.
- CAD hand-off via DXF, which is inherently a 2D geometry format.
When 3D earns its place
RoomPlot gives you three 3D view modes - Realistic, Technical and Wireframe - and two sources: a Live 3D scene rebuilt from your current plan, and, on LiDAR-scanned floors, the Original 3D scan. You can edit in 3D too: set wall heights and ceilings, and drag elements with a live dimension overlay. Reach for 3D when you want to:
- Show a client what a room will feel like, not just its footprint.
- Check ceiling heights, reduced headroom or sightlines.
- Export an interactive USDZ model from a LiDAR scan for AR viewing.
Tip. Work in 2D for speed, then jump into 3D to sanity-check heights before you export. Undo and redo work in both views, and an undo in 2D propagates into the live 3D scene, so it is safe to experiment.
You do not have to choose
The real advantage is that both views come from one plan. Draw or scan once, edit in whichever view suits the task, and export the right deliverable for each audience: a 2D PDF or image for clients and trades, DXF for CAD, and USDZ for 3D and AR. Nothing is duplicated, so the 2D and 3D versions can never drift out of step.
