3D at iPad not possible?

Hi @Paul3138957794n4,

Hope you are doing well. Thank you for writing in!

By 3-D files, do you refer to multi-layered files? Such files are only supported on the desktop version of the application due to the heavy metadata on the files, which cannot be processed entirely on mobile processors. 

We would like to know more about the feature. Please fill out the form: https://acrobat.uservoice.com/

Filling out the form ensures that your feedback reaches our product team to review and implementation in the future updates.
