Place in the World

Place in the World



Now that you know how to utilize the science simulations and digital teaching aids on the Merge EDU Platform, we can start using some of the additional features the apps offer! 

Object Viewer has a special feature called “Place in the World”, which allows users to scan a nearby surface and virtually “place” a 3D object in their environment. This feature allows you to view 3D objects without the Merge Cube, and to see what objects look like at full-size in your room. You can even place multiple objects side-by-side to create a scene or compare and contrast.

In this article, you will learn about:

  • How to Place a 3D Object in Object Viewer
  • Movement Controls in Object Viewer
  • Other Controls in Object Viewer

When you’re ready to start, just follow these steps:

How to Place an Object in Object Viewer

  1. Launch the Object Viewer app and select a 3D Object.

  2. Tap the mode toggle at the top of the screen to swap to “World”-mode.

  3. Scan a surface until you see a white circle form. Make sure that there is enough visual data in the area you are scanning for your device to pick up depth. Once the circle appears, tap the circle to place the object in the world.

  4. Tap the object you placed in the world to engage the movement controls and adjust the positioning of your hologram.

  5. Place several different objects next to each other to compare and contrast.

Movement Controls

There are a few ways to move your 3D object once you have placed it in the world. Read about them below:


Tap the object you wish to move to select it (it will be highlighted in white when selected). Then, use one finger to move the object along the X or Z axis (back-and-forth or side-to-side).


With the object selected, place two fingers on either side of the object, then turn them clockwise or counterclockwise to rotate the object on the Y axis.


With the object selected, place two fingers on the object, then slide them up or down to move the object along the Y axis.


With the object selected, place two fingers on the object, then pinch them together to scale the object down or spread them apart to scale the object up.

Other Controls

Object Viewer has some other helpful controls you will need to use when placing objects in the world. Read about them below:

Clear All

Use the “Clear All” button (located in the bottom left corner of the screen) to delete all placed objects in your environment.


When you tap on an object to select it, the “clear all” button becomes a “Delete” button. Use the delete button to delete a single object.


To the right of the delete button is the “Pedestal” button. The pedestal button creates a black, cylindrical pedestal beneath the object. You can increase the altitude of the object to extend the pedestal.

Place and Cancel

The “Place” (and “Cancel”) button to the bottom-right of the screen allows you to enter and exit place-in-world mode. Tapping the place tool will show the white circle again, allowing you to place another 3D object onto the scene. The cancel button will remove the white circle so you can see your scene in full.


The “Exit” button at the top-right corner of the screen will take you back to the Collection View or Object View page. 

Note: The Place tool will remember any object you placed, so you can navigate to another collection or 3D object and place it on the same scene. If you do not want to continue working with the same scene, be sure to “Clear All” or “Delete” the objects from your scene before continuing.


Now that you’ve learned how to place objects in your environment, you can walk around the object at full size and view it from all angles. You can even place multiple objects and have a digital museum right in your house or classroom!
