How to Trace an Existing Floor Plan

Stop drawing from scratch. Learn how to upload a photo of your blueprint and turn it into a digital model in minutes.

Transform Paper Blueprints into Digital Designs

One of the most powerful features of RoomyLab is the ability to Trace Plan. Instead of manually measuring every wall with a tape measure, you can simply take a photo of an existing floor plan and draw over it.

Step 1: Upload Your Image

Click the Trace Plan icon (the image plus symbol) in the sidebar. Select a clear photo or scan of your floor plan (JPG or PNG).

Step 2: Calibrate the Scale

An image doesn't naturally know how "big" it is. You need to tell the engine the scale:

  1. Click Point A and Point B on a line of a known distance (like a 3-foot door or a 10-foot wall).
  2. Enter the real-world distance in the popup.
  3. The system will now automatically scale the entire image so that every wall you draw is perfectly accurate.

Step 3: Trace Your Walls

Select the Wall Tool and draw directly over the lines of your uploaded image. The walls will snap into place, creating a 1:1 digital replica of your physical blueprint.

Step 4: Add Furniture and Doors

Once your walls are traced, toggle the Layer Panel to hide the background image. You can now place furniture, windows, and doors to see how a new renovation would look in your actual space.

Pro Tip: If you don't have a blueprint, take a birds-eye photo of a hand-drawn sketch and trace that!
