Step 8 To define which side of the block you want to be pasting your artwork onto, select the corresponding side from the icon in the top left corner of your window. Switch to the Perspective Selection tool (it’s next to Perspective Grid) and select your piece of artwork.
Step 9 As you drag your artwork onto the grid you’ll see the grid affect its perspective. You can place your artwork anywhere on the grid, and resize it to gain the exact perspective required.
Step 10 When your artwork is in perspective as you need it, drag it away from the grid using the Selection tool – this will prevent the perspective from changing. You can still resize the artwork outside of the grid, or drag it back into the grid to alter the perspective.
