How to Render a Floor Plan in 3D — and When a 2D Presentation Plan Is the Better Deliverable

When someone asks to "render a floor plan in 3D," they usually mean one of two very different things. Either they want a three-dimensional model of the house they can orbit, walk through, and show a client — or they want the flat plan to look finished: colour, furniture, flooring, a drawing that reads at a glance in a listing or a presentation. Both are quick on Archify, but they're different tools, and picking the right one first saves you credits and a confused client.

Route A: a real 3D house from the plan (free)

If what you want is a model, draw the walls in Design Studio. As you sketch walls in 2D, a live, fully editable 3D house builds itself alongside — rooms are detected, floor areas and door and window schedules fill in automatically, and elevations, sections, and print-ready sheets come from the same model. It never spends credits, on the free account or any paid plan.

1. Start from what you have. Drop a .dwg or .dxf straight in and the walls become real walls. A PDF or a photo of a printed plan works as a tracing base. From Revit or SketchUp Pro, export a floor-plan view to DXF first.
2. Fix the layout by chat. "Add a bathroom off the primary bedroom," "move the front door to the left bay," "raise the roof to 9 feet" — the studio applies it to the model.
3. Walk it. First-person walk in the browser, or a VR preview with a headset. This is a true 3D camera through a true model, so what the client sees is exactly what you drew.
4. Export. DXF for any CAD app, IFC for Revit or ArchiCAD, GLB for any 3D or real-time tool, CSV for the schedules.

Route B: a coloured, furnished 2D plan for the deck

If the deliverable is the plan itself — a listing, a marketing board, a client deck — use Floor Plan Render. Upload any plan image (a PNG from Design Studio or AI CAD, a flattened CAD export, a scan, a hand sketch) and it returns a coloured, furnished, presentation-quality plan with the wall layout preserved, for 100 credits. It reads the picture, not a file format, so there's no conversion step.

• Keep the Faithful ↔ Creative slider at its default. Faithful holds every wall and opening where you drew it; Creative lets the AI reinterpret — which is rarely what you want on a plan a client has already approved.
• Export the plan from Design Studio at a clean, high-contrast size before rendering. Thin grey walls on a busy background give the model less to hold on to.
• Render per level. One plan per run keeps the furniture scale consistent and makes a redo cheap.

Doing both: draw, then render

The workflow most practices settle on: draw the walls in Design Studio (free), walk it to confirm the layout, export a PNG of the plan, and render that PNG once the layout is agreed. The model gives you geometry you can measure and export; the rendered plan gives you the picture that sells it. Neither tool pretends to be the other — a rendered plan knows nothing about your model, and the model never spends a credit to exist.
