Trace an existing plan

If you already have a drawing of the home, such as an estate agent's plan or a scan from a builder, you can place it under the plan and trace over it. Images (JPG, PNG or WebP) and PDFs are accepted. You trace the walls yourself; automatic plan recognition is in development and not available yet.

Steps

1. Open the Build panel and scroll to Trace a floor plan.
2. Click Upload plan image or PDF and choose the file. For a PDF, the first page is used.
3. For a PDF, type the Drawing scale 1:n printed on the drawing, such as 100 for 1:100. A PDF starts at 1:100. You can type the sheet's real width instead.
4. For an image, type the Image width in real life: the real distance the whole image covers, side to side.
5. Use the Opacity slider so you can see both the drawing and your walls.
6. Draw over it with the Room and Wall tools. See Draw walls and rooms.
7. Click Remove image when you have finished.

Tips and limits

• To find an image's real width, measure one wall you know on the drawing and scale up. For example, if a 4 m wall spans a fifth of the image's width, the image is 20 m wide.
• Check a few walls with the Measure tool (M) after scaling. If they are off, adjust the width or scale.
• Photos taken at an angle distort the plan. Scans or straight-on photos trace best.
• If a PDF has several pages, a note tells you that page 1 is shown.
• Everything happens in your browser; the file is not uploaded.
