AI Floor Plan Tracing

Five steps from picture to model

You only need a floor plan image and one length you know.

1

Upload your floor plan

Use a JPG or PNG of your plan. Imported a listing? Choose “Use saved floor plan” and skip the upload.
2

Set the scale with one line

Click both ends of a wall whose real length you know and enter that length. It is the only measurement Spatium needs.
3

Choose the floors

Select one or several floor levels, from basement to upper floors. The traced layout is created on each of them.
4

Let the AI trace it, or trace by hand

AI Auto-Trace (beta) detects walls, doors and windows and builds the rooms. Prefer full control? Click the corners of each room yourself.
5

Pick the construction and refine

Choose wall, floor and ceiling constructions for all new rooms in one step, then fine-tune the result in the 2D editor and the 3D view.

Two ways to trace

Use whichever fits the plan in front of you. Both end in the same editable rooms.

Beta

AI Auto-Trace

The AI reads your plan and builds the rooms for you: walls, doors and windows in one pass.

✓ Fastest way to a complete layout
✓ Works best on clear, high-resolution plans
✓ Expect to review and adjust the result

Always available

Manual Trace

Click the corners of each room on your plan and Spatium builds the walls from your outline.

✓ Full control over every corner
✓ A good fallback for sketches and unclear plans
✓ Uses the same scale and floor selection

One step, all new rooms

Define how it’s built

Right after tracing, Spatium asks how the new rooms are constructed. Choose a wall, floor and ceiling construction once and it is applied to every room that was just created.

✓ Standard constructions: for example drywall or timber stud partitions, oak parquet or ceramic tiles, painted or suspended ceilings.
✓ See the layers before you choose: each option lists what it is made of, such as finish, substrate and frame.
✓ The basis for your costs: the layers you pick feed the cost estimate and the material shopping list.
✓ Not sure yet? Skip it and create an empty shell, then add constructions later.

What you get

Not just lines on a picture: rooms you can edit, measure and cost.

Rooms, walls, floors and ceilings

Every traced room comes with its walls, floor and ceiling, each starting from a standard construction you can change.

Doors and windows in place

With AI Auto-Trace, detected doors and windows are positioned on the walls they belong to.

A starting name for each room

Rooms are named from their size and openings, for example Bathroom, Bedroom, Hallway or Living Room. Rename them anytime.

Real dimensions

Everything is scaled from the length you entered, so room sizes and floor areas are meaningful from the start.

Ready for costing

Cost estimates and material shopping lists follow from the constructions you choose, with no extra data entry.

Your plan stays with the project

An uploaded plan is saved to the project by default, so you can trace again later. Replace or remove it whenever you like.

Good to know

What tracing does today, so there are no surprises.

AI Auto-Trace is in betaResults depend on the quality of your plan. Clear, high-resolution plans work best, and you should expect to review and adjust the result.
If nothing is recognisedYou are told right away and can try a clearer image or trace by hand. A plan that produced nothing is not saved to your project.
Room names are a starting guessThey come from room size and the number of doors and windows. Spatium does not read the text printed on your plan.
The scale comes from youDimensions are as accurate as your plan and the reference length you enter.
ImagesTrace from JPG or PNG images. Floor plans delivered as PDF are not supported yet.
Several floors get the same layoutTracing onto multiple floor levels creates the same rooms on each, which suits identical storeys. Adjust each floor afterwards.

Questions about tracing

Do I need exact dimensions of my home?

No. You enter one length you know, such as the length of a wall, and everything else is scaled from it.

What if the AI gets a wall wrong?

Correct it in the editor, or remove the rooms and trace by hand. AI Auto-Trace is a head start that you review, not a replacement for a quick check.

How long does a trace take?

Typically about half a minute for a floor once the AI service is warm, depending on the size of the plan. The first trace after a quiet period can take up to about a minute and a half while the service starts. The result is a starting point that you review and correct in the editor.

Can I trace a floor plan that came with an imported listing?

Yes. The imported plan is saved with the project, so choose “Use saved floor plan” in the tracer. See the listing import feature for how plans are imported.
