Create a 3D object

Note: 3D objects are supported only on iOS

On Android and Windows, you can create HTML5 files that does the 3D on all the OS. 

The requirements to add a 3D object in your app are the following:

- the 3D model should follow the .obj standard: https://en.wikipedia.org/wiki/Wavefront_.obj_file
- ⚠️  the .obj file and its optional material .mtl file should be included at the root of a .zip file.
To do so, make sure to select all the files (not the folder itself) including the .obj and .mtl before compressing them. 
- the .obj file should be named model.obj
- the number of polygons and the materials should depend on the processing power provided by the device

When these requirements are met, the resulting .zip file should be added as a new document wherever you want in your contents.
