LiDAR scan: Measure rooms in minutes
The LiDAR scan automatically captures room geometries using an iPhone or iPad Pro. You can edit the results in the integrated floor plan editor or create the floor plan from scratch using drawing tools or AI recognition.

2,000+ companies rely on our LiDAR scan.

How does the LiDAR scan with autarc work?
The scan captures room geometries using the LiDAR sensor on your iPhone or iPad Pro. autarc automatically converts the scan data into an editable 3D model in the floor plan editor and uses it to calculate heat load and hydraulic balancing. You scan the building on-site, and autarc processes the data in the background.
- Scan room: You guide your iPhone or iPad Pro through the room once. A user guide leads you through the process step-by-step with helpful prompts. The LiDAR sensor captures walls, ceilings, and floors in seconds.
- Create 3D model: autarc automatically converts the scan data into a digital building model.
- Review model: You review the model and adjust details on your device as needed.
- Calculate heat load and balancing: autarc automatically uses the model to calculate the heat load according to DIN EN 12831 and the hydraulic balancing according to Procedure B.
Scan easily, plan instantly
Flexible building data capture

1. Scan buildings via LiDAR
Capture rooms directly on-site using your iPad or iPhone. Walls, doors, windows, and room dimensions are automatically detected and imported into autarc as a digital floor plan.
2. Detect floor plans via AI
Upload an existing floor plan. The AI automatically identifies rooms, walls, windows, and other building data, converting them into an editable digital floor plan.
3. Draw floor plans yourself
Create a floor plan directly in the editor or trace an existing template. Dimensions and building elements can be customized individually.
4. Use directly for planning
Regardless of how the building data was captured, it is immediately available for further planning in autarc.

Benefits of LiDAR scanning with autarc
- Scan individual rooms in 30 to 45 seconds. Houses up to 175 m² can be scanned in less than 15 minutes.
- Millimeter-level measurement accuracy instead of reading errors from tape measures or laser distance meters.
- Save over 20 hours per project compared to traditional measurements and manual calculations.
- Over 10,000 single-family homes already scanned with the autarc LiDAR scan.
- Plan new builds or remote projects using drawings or AI recognition.
- Works regardless of lighting conditions, even in dark basements or at twilight.
LiDAR scan FAQs
What is the LiDAR scan in autarc?
LiDAR scan is the feature in the autarc app that allows you to automatically capture room geometries using your smartphone or tablet. The scan data opens directly in the floor plan editor and is integrated into heat load calculations, hydraulic balancing, and heating system design.
Which devices support LiDAR scanning?
Supported devices include the iPhone 12 Pro, 13 Pro, 14 Pro, and 15 Pro, as well as all iPad Pro models from 2020 onwards. These devices are equipped with the necessary LiDAR sensor.
How accurate is LiDAR surveying?
The scan measures walls, ceilings, and floors with millimeter precision. This is sufficient for standard-compliant heat load calculations without the need for manual re-measuring.
How long does a complete building scan take?
Individual rooms take 30 to 45 seconds. You can scan a 175 m² house completely in about 15 minutes.
Does the LiDAR scan work without an internet connection?
Yes, the scan runs completely offline. As soon as a connection is re-established, autarc automatically synchronizes the data to the cloud.
Can I create a floor plan without a LiDAR scan?
Yes, you can draw the floor plan manually in the floor plan editor or upload an existing plan, which autarc will automatically analyze using AI floor plan recognition.
Is this also suitable for new builds?
Yes, you can draw the floor plan or upload the building plans even before the building is constructed.
LiDAR scan or photogrammetry: What is the difference?
LiDAR scan captures interiors for heat load calculations and hydraulic balancing. Photogrammetry creates a 3D model of the building envelope from drone photos for PV planning. Both methods complement each other but cover different planning applications.
