Save writes the current plan to a JSON file. Load reads one back in.

Display
Units
Switches every size field and dimension readout in
this menu and in every object dialog. The
underlying plan is always stored in meters, so
this is just how it's typed and displayed.
Add 3D object
Pick a .glb / .gltf file from your computer.
Mounted on the selected wall if any, at the
selected room's centre otherwise, else at
scene origin.
Add room
Adds a 10×10 room east of the current
building with an auto-generated name. Use the
room's dialog afterwards (click it) to rename,
resize, or reposition it precisely.
Wall height
Each click changes every room's ceiling height
by 0.5 m (clamped to 1.0–10.0 m). Undoable.
Validate
not run
Pair a new Zigbee device
Opens pairing mode for 60s — have whoever is at the
building press the join button on the new sensor
now. A naming dialog pops up automatically once
it's paired.
View schematic
Opens a 2D block diagram of that object's HAL
controls, wiring, and live input/output values in a
panel at the bottom of the screen.
No alarms yet.
Add an alarm to a door or window from its scene
object, then arm it here. When an alarm trips, an
acknowledge box appears.
Ask AI to edit the building
Needs Ollama running locally with a Gemma model
pulled (edit OLLAMA_MODEL near the top of the script
if your local tag differs from "gemma4"). Only adds,
updates, or deletes doors/windows — nothing else.
Decision needed
Room
Rename
Resize (m)
w:d:
Grows or shrinks from this room's NW corner — that
corner stays fixed in place; only the east and
south walls move. Applies as soon as you change
either field.
Floor color
Tints this room's own floor tile independently of
every other room's — they all share the same tile
texture underneath, so this doesn't cost any extra
texture memory per room.
Wall
Add opening (m)
pos (0–1):width:
Wall piece (m)
len:pos:
A wall's physical span can be shorter than the
room's side and can sit anywhere along it — the
uncovered part is open (no wall), which is how
you carve out an opening. "pos" is the distance
from the wall's start corner to where this piece
begins. A wall can hold more than one piece with
a gap between them. You can also just drag a
piece directly in the 3D view to slide it —
dragging never resizes the room, only the
Resize room dialog does that.
Delete wall
Interior wall: merges the two rooms it separates.
Exterior wall: removes it and leaves the room open on that side.
Opening
Delete opening
Removes this door or window. The wall stays put;
only the hole goes away. Shortcut: Delete / Backspace.
