How to get a floor plan into AutoCAD

Updated 13 July 20265 min read

There are two ways to get a floor plan into AutoCAD: attach an image or PDF as a scaled underlay and trace it, or convert the plan to DXF/DWG and open it as native, editable geometry. The second is faster to actually work with, because you skip the tracing entirely.

Option 1 — Attach an underlay and trace

Attach the image or PDF in AutoCAD (as an external reference / underlay).
Scale it to a known dimension.
Trace walls and openings on proper layers.

Works everywhere, but you're still redrawing by hand.

Option 2 — Convert to DXF/DWG and open it

Turn the plan into editable CAD geometry first, then just open it:

Upload the image or PDF plan.
Detection rebuilds the walls, rooms, and openings.
Export layered DXF or DWG (see also PDF to DXF and image to CAD).
Open the file natively in AutoCAD and keep working.

Upload an image or PDF plan and export clean, layered CAD — no tracing, no CAD license to create it.

Tips

Prefer DWG/DXF over an image whenever you actually need to edit — an underlay is just a picture.
Lock the scale early from a known measurement.
Keep layers clean so walls, doors, and text stay separable.

Frequently asked questions

Can you open a floor plan image in AutoCAD?

You can attach an image or PDF in AutoCAD as an underlay to trace over, but it isn't editable geometry. To get editable walls you either trace the underlay or convert the plan to DXF/DWG first and open that natively.

What's the best format to bring into AutoCAD?

DWG or DXF, because AutoCAD opens them as native, layered vector geometry. Convert an image or PDF plan to DXF/DWG first — Extruda produces this directly.

Does AutoCAD import PDF floor plans?

AutoCAD can import PDF geometry, which works well for vector PDFs but poorly for scanned ones. For scans, AI detection or tracing gives a cleaner, layered result.

How do I keep the scale right in AutoCAD?

Set the scale from a known dimension when you convert or when you attach the underlay. Getting scale right up front avoids re-doing the whole drawing.
