View predefined 3D shapes in mixed reality
Use the View shape in MR control in a canvas app to see whether a digital cube of a given size fits in a real-world space. (To compare a 3D model of an object instead, use the View in MR control.)
The View shape in MR control adds a button to your app. When a user selects the button, the app overlays a cube on the device camera feed. The cube's dimensions are set as a property on the control when you author the app in Microsoft Power Apps Studio. Users may not change the size of the cube while they use the app.
Tip
The mixed-reality (MR) controls work best in well-lit environments with flat-textured surfaces. Tracking is better on LIDAR-enabled devices.
Tip
The MR controls in Power Apps use Babylon and Babylon React Native. Mixed reality content that works in the Babylon sandbox should work in Power Apps through this shared MR platform. If your content works in Babylon but not in Power Apps, ask a question in the Power Apps Community Forum. (Tag it with "mixed reality.")
Add a View shape in MR button to an app screen
With your app open for editing in Power Apps Studio:
- Open the Insert tab and expand Mixed Reality.
- Select View shape in MR to place the control in the app screen, or drag the control to the screen to position it more precisely.
The control is a button that's labeled with an icon of a cube and the text Place a cube. Change the label and hide the icon if you like in the Text and Display type properties.

Output properties
Your app can make use of more properties when a user interacts with the View shape in MR control. These are known as output properties. You can use these properties in other controls or to customize the app experience.
| Property | Description | Type |
|---|---|---|
| Photos | Collects the photos captured during the mixed reality session. You can upload the mixed-reality photos to OneDrive and show them in a gallery. | Not applicable |
