How to import cadastral GeoJSON

Use this guide when you already have a cadastral GeoJSON downloaded from app.qubu.io and need it in Studio as the project boundary.

TODO screenshot: show a cadastral GeoJSON import result, with the site boundary selected in the left tree and the parcel shape highlighted in the viewport.

Prepare the file

1. Download the cadastral GeoJSON from app.qubu.io.
2. Keep the file unchanged until you confirm the import works.
3. Close any running generation in Studio before you import.

Import the cadastral boundary

1. Open Main menu → Import → Import GeoJSON....
2. Select the downloaded cadastral GeoJSON file.
3. Let Studio import it as Site boundary.
4. Wait for the boundary to appear in the left tree.

Check the imported site immediately

1. Select the boundary in the left tree.
2. Confirm the boundary shape matches the parcel you expected.
3. Check the Z coordinate in Properties only if the site must align to imported context or an existing scene.
4. Fit the view with F.

Continue only after the boundary is confirmed

• Import surroundings after the cadastral boundary is correct.
• Set canvas rotation and north offset after the boundary is in place.
• Start massing generation only after you trust the imported parcel.

For the import fields and save/export behavior, use the Importing, exporting, and project files reference.
