Uploading a Substrate

When starting work on a new project, it's important to accurately recreate the layout of the space. One of the most convenient ways to do this is by uploading a Substrate — an image of a floor plan (e.g., a measurement plan or hand-drawn sketch) that helps you build walls with precision.

What is a Substrate?

A substrate is an image of the room layout uploaded into the 2D workspace of the editor. You can trace over it to draw walls based on real measurements and the room’s configuration. This is especially helpful when working from on-site measurements.

How to open the substrate settings window

There are two ways to open the upload and settings window for the background:

• via the menu «Construction» → «Substrate»
• using the shortcut Shift + V

Uploading a substrate

To upload a background image, click the «Upload floor plan» button in the substrate window.
You have two upload options:

• From your computer — select a file in PNG, JPG, or JPEG format.
• By URL — paste the direct link to the image.

Substrate visibility settings

After uploading, you can control the visibility of the substrate:

Show / hide background — use the eye icon or press the V key
 

Rotating the background

If the uploaded image is rotated incorrectly (e.g., 90° off), you can adjust it using the «Rotation» field by entering the correct angle.

Setting the correct scale

To ensure your plan matches real-world dimensions, you need to set the correct scale using the «Section» tool:

1. Align the orange endpoints of the segment with a known object on the plan — for example, a doorway.
2. Enter the real length of that object in the «Section size» field.
3. The app will automatically adjust the scale of the substrate.

Resetting the substrate

If the segment with orange points is not visible or the background is misaligned, click the «Reset» button. This will restore the background to its original position and re-center the segment.
