Open a 2D image and select the layer that you want to convert to a 3D shape.
Choose 3D > New Shape From Layer, and select a shape from the menu. Shapes include single-mesh objects like a donut, sphere, or hat, as well as multiple mesh objects such as a cone, cube, cylinder, soda can, or wine bottle.
Note: You can add your own custom shapes to the shape menu. Shapes are Collada (.dae) 3D model files. To add a shape, place the Collada model file in the Presets\Meshes folder inside the Photoshop program folder.
