This question already has an answer here:
I'm trying to learn how to make 3D Box Images in Photoshop. I need this for box designs of different sizes, and so I found this tutorial that makes it easy to create with the use of Photoshop Actions.
While fast-reading the tutorial, I found around Step 10 onwards, the shape of the box is explained on how to shape it... For me, I need these shapes of different sizes (varied length, depth, and height).
How can I set the shape to be varied on user's input? For example, when the action is running, how can I alter the tutorial's method to ask user input for the length, depth and height?
Also, is there ANY software (free/paid) that can let me create these boxes hassle-free? Any Action/script/template in Photoshop that can let me change the dimensions as per requirement?
