Build a Floor from Room Scans

1 · Import a measured room

Choose OpenPlan JSON

The first accepted scan becomes the root room. Upload one room at a time—or choose several JSON files together. Every later room waits for you to choose exactly where it connects.

Room name Choose one or more room JSON files

No file chosen.

Import evidence will appear here.

2 · Place the next room

Scan or upload the next room

When another room arrives, choose the existing room it joins and connect the two measured boundaries. A preview moves the new room rigidly; neither scan is resized.

Connect directly on the 2D plan

After the next room is imported, tap its wall and the matching wall on the connected floor—in either order.

Junior room Host room Host boundary start Host boundary end Junior boundary start Junior boundary end Advanced: connect by an interior closet/inset run

Rooms connect on their four outer walls. Use the same start and end for one wall. Choose consecutive first and last walls to align a jagged closet or multi-wall boundary without flattening it.
