Door widths

Measures every doorway and flags the ones too narrow for you or what you are moving.

What it answers

• Can my wheelchair get through every door?
• Will a 90 cm sofa fit through?

For the agent, the tool is described as: Check every doorway and open passage in one scan against a minimum width. Returns one check per doorway, findings for the ones that fail or are close, pins and a coloured rule overlay.

Who it is for

Apartment manager, Daycare operator, Facility manager, Fire captain, Moving large furniture, Office tenant, Older adult or family, Parent of a toddler, house with a pool, Truck dispatcher, Wheelchair user, Wheelchair van owner.

Inputs

Input	Type	Required	Default	Notes
scan	string	yes		Scan id. Filled from the selected building.
min_width_m	number (m)	yes		Asked as: “How wide a door do you need, in metres? For furniture, use its narrowest side; a wheelchair needs 0.813 m (32 in).” Saved preference access.door_width_m. Range: more than 0.3, at most 3.0.
warn_margin_m	number (m)		0.05	Doorways this close above the threshold are a warning. Saved preference access.door_warn_margin_m. Range: at least 0, at most 0.5.
standard	string			The rule the threshold comes from. Saved preference access.door_standard.

An input that nothing fills (the selected building, a saved preference, a persona’s preset) becomes a question to the person. The agent asks only for those.

Data used

Layer	Id	Needed	If it is missing
Doors and windows	matterport.openings	required	The verdict is unknown, with the reason.
Room names	matterport.room_labels	optional	The tool runs without it.

What it returns

A tool result: a verdict (pass, warn, fail or unknown), metrics, checks and findings, each with its source.

• Draws on the building: pins on what it found; doors, walls or rooms coloured by status.
• Panel blocks: VerdictHeader, MetricRow, CheckList, FloorPlanMini, Controls, AssumptionChips, StepLog, ActionBar.
• Speed: fast. Read-only.

How it works

Every doorway’s width against a threshold, as checks, pins and a pass/warn/fail rule overlay.

Reliability

Sources this tool gave on the test home:

Where it came from	Layer	Method	Reliability	Note
Measured from the scan	matterport	geometry	medium	Opening width in the wall graph; a hinged door’s leaf takes a few centimetres off it

The tool sets the label for each value. A model never does. The tools give a scan’s wall graph the layer matterport whichever device made the scan, so a phone scan’s geometry carries that label too.

Limits

• Needs: doors and windows. On a scan without it, the verdict is unknown and says why.
• A result is a planning aid, not an inspection.

On the made-up test home

This section was written by running the tool when the docs were built, on a hand-made RoomPlan export (no real place was scanned), with no sponsor keys and the network switched off.

Inputs used: min_width_m = 0.813 (preset of the persona “Apartment manager”).

Fail 3 of 6 doorways are narrower than 0.813 m.

Value	Result	Where it came from	Reliability
Doorways	6	Measured from the scan	medium
Narrowest	0.71 m	Measured from the scan	medium
Too narrow	3	Measured from the scan	medium

Check	Measured	Against	Status
Doorway width, Bathroom to Hallway	0.71	0.813 m	fail
Doorway width, Hallway to Bedroom	0.76	0.813 m	fail
Doorway width, Living Room to Bedroom	0.81	0.813 m	fail
Doorway width, Hallway to Living Room	0.86	0.813 m	warn
Doorway width, Living Room to outside	0.91	0.813 m	pass
Doorway width, Kitchen to Living Room	1.2	0.813 m	pass

Findings: 3 fail, 1 warn.

What it reported while it ran:

1. Found 6 doorways and passages in the wall graph
2. Compared each with 0.813 m: 3 fail, 1 close
