Floor plan to CAD, 3D & every export format

One floor plan can become a dozen different files — a layered CAD drawing, a 3D mesh, a vector, a printable model. The trick is picking the right format for the tool you're feeding. This guide maps every export, says which is native and which is a quick conversion, and links the step-by-step for each.

The short version

Match the format to where it's going:

glTF / GLBWeb, AR, real-time 3DNative export

The important distinction across all of them: you're exporting editable geometry, not a flat picture. The hard part — reading walls, rooms, and openings off the plan — happens once; the format is just how you carry that geometry into the next tool.

CAD formats: DXF & DWG

DXF and DWG are the backbone of professional drafting — layered, scaled, editable line geometry. They're what you want whenever the destination is AutoCAD, Revit, or any CAD workflow.

3D mesh formats: OBJ, glTF/GLB, .blend, STL, FBX

Once the plan is a 3D model, the mesh formats are about where the model is going — a 3D app, the web, a game engine, or a printer.

  • OBJ — the most universal mesh; opens almost anywhere.
  • glTF / GLB — the "JPEG of 3D," ideal for web, AR, and real time.
  • .blend — a native Blender scene for detailed editing and rendering.
  • STL — for 3D printing a physical model of the plan.
  • FBX — for Unreal, Unity, and game-ready 3D.

Vector: SVG

Sometimes you don't want 3D or CAD at all — you want clean, scalable line art of the plan for a website, a brochure, or a diagram. That's SVG: infinitely scalable, tiny, and styleable with CSS.

Which format should I use?

  • Drafting / construction docs → DXF or DWG.
  • Opening in a 3D app → OBJ (universal) or .blend (Blender).
  • Web, AR, or a real-time viewer → glTF / GLB.
  • Game engine → FBX (or glTF).
  • 3D printing → STL.
  • Flat vector graphic → SVG.

Frequently asked questions

What formats can you export a floor plan to?

From one floor plan you can export CAD (DXF/DWG), 3D mesh (OBJ, glTF/GLB, .blend), and vector (SVG) directly. STL for 3D printing and FBX for game engines are a one-step conversion away from the 3D model. Which you pick depends on the tool you're feeding — AutoCAD/Revit want DXF/DWG, Blender wants .blend, the web and AR want glTF.

What's the best format for AutoCAD or Revit?

DXF or DWG. Both are the native CAD exchange formats — layered, scaled, editable line geometry that AutoCAD opens directly and Revit imports as an underlay or a basis for native elements.

What format do I need for 3D printing a floor plan?

STL is the standard 3D-print format. Export the plan as a 3D model (OBJ or .blend), make sure it's watertight, then convert to STL and send it to your slicer.

Can I get an editable file instead of just a picture?

Yes — that's the point of exporting to a real format. DXF/DWG give you editable CAD geometry, .blend gives you an editable 3D scene, and OBJ/glTF give you a mesh you can modify. None of these is a flat image; they're geometry you can measure, edit, and build on.
