In this video you’ll learn the basics of 3D in Photoshop CC. Learn how to turn a simple layer into 3D, manipulate it, use Illustrator graphics to extrude and warp, and then take those 3D graphics to be printed in the material of your choice, all from Photoshop CC. You’ll also be introduced to Strata Design 3D for simple 3D manipulation.
Update: Here is the iPhone 5 case for download. Just customize it (select Edit Source for the design layer) and send to Shapeways.com! (At your own risk of course.)
