3D Floor Plan Creator
Draw in 2D, See It in 3D — Free
Draw your floor plan with exact dimensions and see it as a 3D house at the same time — walls, doors, windows, floors and roof. Walk through the rooms, then export dimensioned PDF and DXF drawings. Free, in your browser.

Key facts
- What it is
- A free 3D floor plan creator in the browser: one model gives both the dimensioned 2D plan and the 3D house.
- Accuracy
- Exact wall lengths (typed), real wall thickness, room areas in m², doors and windows placed by distance.
- Views
- 2D plan, 3D view, split 2D + 3D view, and an eye-height walkthrough.
- Export
- Dimensioned floor plans and elevations as PDF and DXF (CAD layers); materials list in Excel.
- Have a drawing?
- DWG, DXF, SketchUp and IFC open directly; photos and PDF plans are built in 3D by the Geoniks team, free.
One model: the 2D plan and the 3D house
In many tools the 3D view is a picture made from the plan. In Geoniks the plan and the 3D house are the same model. Every wall has a length, a height, a thickness and a construction type (log, timber frame, post & beam, CLT), so the 3D floor plan is accurate enough to price and to turn into builder drawings.
What you can do
- Exact walls — type 5.2, 520cm, an angle like 5<90 or a point like @3,0; arrow keys lock the direction.
- Rooms and areas — closed rooms show their area; move a wall and the rooms follow.
- Doors, windows, stairs — placed on walls with exact distances, visible in 2D and 3D.
- Roof and floors — gable, shed and other roofs; several floors; decks and porches.
- Walkthrough — walk through the 3D floor plan at eye height on a computer or phone.
- Drawing set — PDF and DXF floor plans and elevations, materials list in Excel.
How to create a 3D floor plan in Geoniks
- Start a plan — blank, from a ready wooden house, or from a DXF file.
- Draw the outer walls — press R for a rectangle and type the size, e.g. 8,10 for 8 × 10 m.
- Add inner walls, doors and windows — rooms and their areas appear as walls close.
- Switch to 3D or split view — check heights, openings and the roof; walk through the rooms.
- Export the plan — a PDF and DXF drawing set, or ask manufacturers for a price.
Frequently asked questions
How do I make a 3D floor plan for free?
Open Geoniks in your browser, start a plan and draw the walls in 2D — type exact lengths such as 5.2 or 520cm. The 3D view builds itself as you draw: walls, doors, windows, floors and the roof appear in 3D at the same time. It is free and nothing is installed.
What is the difference between a 2D and a 3D floor plan?
A 2D floor plan is the view from above with wall lengths, rooms and areas — what a builder reads. A 3D floor plan shows the same plan with real wall heights, openings and the roof, so you can judge the space, light and proportions. In Geoniks both are the same model: change one and the other follows.
Can I see the 2D plan and the 3D view side by side?
Yes. Switch between 2D, 3D and a split view where you draw in the plan and watch the 3D house update next to it. You can also walk through the rooms at eye height.
I have a floor plan drawing already. Can it become 3D?
Yes. AutoCAD DWG and DXF, SketchUp and IFC files open directly in the editor. For a photo of a sketch, an architect’s plan or a catalogue plan (JPG/PNG/PDF), the Geoniks team builds it as an editable 3D wooden house for you, free — see “2D floor plan to 3D”.
Can I export the floor plan?
Yes. One click creates a drawing set: dimensioned floor plans and elevations as a vector PDF and as DXF with CAD layers, plus a materials list in Excel.
Does it show room areas?
Yes. When walls close a room, the room and its area in m² appear in the plan; change a wall and the areas update.
