Exporting Objects from Trnio


Trnio is a simple-to-use mobile phone application that converts your photos into 3D models. They let you create, share and discover 3D maps in minutes. Whether focusing on the details of a small object or capturing the gestalt of an entire environment, Trnio is up to the task.

​In this article, we will show you how you can export your 3D-scans from Trnio into a compatible file format for upload onto the Object Viewer app.

Follow these instructions to find out how to export your 3D object from Trnio:


Step 1 - Sign In to Trnio
  1. Open the Trnio app on your device, then Sign-in with your Username and Password.
    • If you do not have a TRNIO account, tap “Join Now” to create an account.


Step 2 - Select the Object you wish to Export
  1. Tap the 3D-scan you want to Export to open the object.

    • If you have not yet created your object, tap the camera icon to start a scan.

    • If you are new to Trnio, check out the tutorials at https://www.trnio.com/tutorial to get started creating your object!


Step 3 - Export the Object into a compatible file type
  1. With your object open, tap the “Export/Share” icon in the top-right corner.

  2. With the “Export/Share” window open, tap “3D Mesh (OBJ)”. Trnio can only directly export OBJ files (contained in a ZIP archive with the associated textures).

  3. Download the object onto your device or send it to your email, SMS, or Classroom Management software of your choice.



Step 4 - Upload your Object using Object Uploader

Now you can sign-in to your Merge Account on the Dashboard and upload your 3D Object using the Object Uploader.
