How can I use my Canvas scan?

The Short Answer

Canvas creates in real-time a scale-accurate 3D model of your room or space, which can be used for a number of different tasks. 

With a Canvas scan, you can (click the links below to jump to the related section):

This is all available for free directly through the Canvas app you tap “Done” after your scan.

The Long Answer

Canvas generates (in real-time) a scale-accurate 3D model which you can see an example of below:

Scan To CAD/Reprocessing

If you’d like us to convert this scan into a professional-grade CAD file, you can now submit this scan to our Scan To CAD pipeline for processing. You can read more about placing an order here: How do I upload my scans for reprocessing or Scan To CAD?

Measuring Tool

Using the measuring tool, you can take any measurement you need within seconds. Tap the ruler icon on the right hand side, then tap any two spots on the scan to measure.

We’ve also included some features to help take measurements. For instance, if you tap two opposing walls (that are parallel to each other), Canvas will automatically snap the measurement to be perfectly perpendicular (that way if you tap too high or too low, you will get the right measurement). 

Notes, Annotations, and Images

Canvas includes the ability to add notes to your scan so you can reference them later when you aren’t actively working with your clients!

For instance, if you want to note a cabinet with a door that needs replacing, tap the sticky note icon, tap the cabinet door and annotate!

You can even add reference images or screenshots using the “Photos” tab.

Please note: The annotations and notes you place on a scan are not uploaded with the scan and will not show up in your CAD file. They are for your reference.


Canvas can also export your scan (before or after reprocessing) as a .obj file, which you can bring into other third-party 3D programs. Exporting an original scan will provide a single .obj file and exporting a reprocessed scan will include a .mtl file and several .jpg files for textures. You must keep these files unzipped and in the same folder as the .obj file. You can learn more about reprocessing here: What is reprocessing and what do I get from it?


  1. Open the scan in the Canvas app
  2. Tap the share button in the top left corner
  3. Select email or AirDrop and select who you want to send it to
  4. The recipient will get a .zip file will all the different scan files (organized by "original" and "reprocessed" scans). 
  5. From here, import the .obj into your software of choice (that supports the .obj format)


Mac users

  1. Connect iPhone and confirm you "Trust" both devices
  2. Open Finder and locate the iPhone device on the left
  3. Click "Files" on the right in the menu bar below your iPhone's name
  4. Click "Canvas" to expand
  5. The file on-device starts with the timestamp of the scan (which is also the default scan name). The naming format is "YYYY-MM-DD-H-M...etc". 
  6. Locate the scan, and drag off the phone to a preferred folder. 
  7. Unzip/unpack the folder completely
  8. Find "", unzip and open the .obj file

PC Users

  1. Download and install iTunes from Apple's website:
  2. Connect your iPhone via USB, open iTunes, and confirm you "Trust" both devices
  3. In iTunes, tap the iPhone icon near the top left, next to "Music"
  4. On the left, click "File Sharing"
  5. Find the Canvas app in the "App List" to the right and click the icon
  6. The file on-device starts with the timestamp of the scan (which is also the default scan name). The naming format is "YYYY-MM-DD-H-M...etc"
  7. Select the scan to export and click "Save" at the bottom. 
  8. In the new window, select where you want to save your file

    Note: Since the file names are very long and can cause issues with Windows, we recommend saving your scan files directly (i.e. no sub folders) to "Local Disk (C:)" 
  9. Repeat for any additional scans
