IFC 4, stable GUIDs
Walls, windows, doors, vents, railings, slabs and beams as IfcWall, IfcWindow, IfcDoor, IfcBuildingElementProxy, IfcRailing, IfcSlab and IfcBeam, with GUIDs that survive re-exports so downstream links do not break.
Features
Everything between the scan and the signed model.
AutoIFC is one workflow: upload, read, fit, review, deliver. The features below are the parts of it you will touch, and what each one does exactly.
Reading
Every element is proposed, then measured.
AutoIFC reads your facade and returns every opening it sees as a box in metres, with a kind and a confidence. Windows, doors and vents are told apart; what cannot be named is kept as its own class rather than forced into one.
Glass is the hard case: curtains and blinds return as many points as the wall does, so an opening is not simply a hole in the scan. Finding them reliably is the part of this that is difficult, and it is the part we do.
Fitting
Every box is measured against your cloud.
A proposal is not a measurement. Each proposed element is measured against the points you uploaded before it reaches you, and the row is settled so that what is delivered is consistent: a door is a door, a window is a window, and two boxes over one opening become one.
Where the scan cannot support a dimension, behind a screen or on a flush shopfront, AutoIFC abstains and says so on the element. That verdict, and its reason, travel with the element into the review and into your IFC.
| Median error | After fitting |
|---|---|
| Along the facade | 7 mm |
| Up the facade | 15 mm |
| Width | 10 mm |
| Height | 50 mm |
| Depth (a declared prior) | 36 mm |
Median absolute error over the 187 paired windows of one named building, against the surveyor's IFC. Per axis on purpose: it tells you the openings are where we say, and that the depth is not a measurement. We publish no single tolerance figure — the Accuracy page says why.
Review
A list, a scene, a decision per element.
The review panel is where the model becomes yours. Filters by status and class, bulk actions behind a confirmation, and a keystroke for every decision.
The rest
Also in the box.
Two IFC variants
The proposal as generated, and the reviewed model built from your decisions. Regenerate the reviewed one as often as you change your mind.
Per-class visibility
Show or hide windows, doors, walls or the unclassified boxes in the viewer, with the scan on or off underneath.
Scan preview before the run
The point cloud appears in the viewer as soon as the upload is processed, so you can check the scan before spending a credit.
Share links
A read-only link to the viewer for a client or a colleague, with the camera and the visible classes you chose, optionally behind a password, optionally expiring.
REST API and webhooks
Create projects, upload or pull scans, launch runs, fetch deliverables and push them to your storage, with signed webhooks for every state change.
Credit ledger
Every charge, grant and purchase is a line you can read. The unit is the square metre of facade modelled, charged when you download the IFC.
Minutes, not days
On the reference building in production: 150 million points in, a reviewable model out, fourteen minutes from launch to the IFC.
Scoring against your model
Give the run a reference IFC and it reports recall, precision and correctness per class, the same table we publish.
