How to convert a 2D floor plan to Revit

Updated 13 July 20266 min read

There are two ways to get a 2D floor plan into Revit: bring it in as a scaled CAD underlay (DXF/DWG) and model native BIM elements over it, or use an AI Revit add-in that generates native walls and openings from the plan. Either way, the key is starting from clean, correctly scaled geometry rather than a flat image.

The underlay route (most common)

Export a clean, layered DXF or DWG of the plan. If you only have an image or PDF, convert it first (see PDF to DXF).
Link or import the DXF/DWG into Revit and set it to the correct scale.
Trace native Revit walls, doors, and windows over the underlay.
Remove the underlay once the model is built.

You still model in Revit, but over accurate lines — no guessing dimensions from a picture.

The AI-native route

Revit-specific AI add-ins can detect a 2D plan and place native BIM elements automatically. That gets you further than an underlay, at the cost of relying on a Revit-only tool. It's worth it when you're processing many similar plans.

Upload an image or PDF plan and export layered CAD ready to underlay in Revit — no manual redraw of the linework.

Tips

Get the scale right before importing. A mis-scaled underlay wastes the whole exercise.
Keep layers clean so walls and openings are easy to trace.
Decide underlay vs native early based on how many plans you're processing — see AI vs manual CAD.

Frequently asked questions

Can you import a 2D floor plan into Revit?

Yes. The most common route is to link or import a DXF/DWG of the plan into Revit as a scaled underlay, then model native walls, doors, and windows over it. AI Revit add-ins can also generate native elements from a 2D plan directly.

What format should I bring into Revit?

DWG or DXF is the standard for a CAD underlay in Revit. Export a clean, layered DXF/DWG from your plan first — Extruda produces this directly from an image or PDF.

Does converting to Revit give native BIM walls automatically?

A CAD underlay gives you accurate linework to trace, not native BIM objects. To auto-generate native Revit walls and openings, use a Revit-specific AI add-in. Either way, starting from clean geometry saves the most time.

Do I need to redraw the plan by hand in Revit?

Not from scratch. With a scaled DXF/DWG underlay you trace over accurate lines instead of guessing dimensions, which is far faster than starting from a flat image.
