opening a photoshop cc 3d stl file in Cura to create gcode

Hi,

I am trying to print a 3d stl file that I created in photoshop.

But when I open the file in Cura and press the layers option the object disappears and no layers are made.

Has anyone any experience with using Cura with a photoshop 3d object?

Thank you!
