Some shapes are more difficult than others to visualize creative outcomes. The cube is one of those shapes for me. But, that doesn't mean it can't be done. For instance, in this project we create a table and part of a chair completely from cubes. Moreover, most of the edges end up not being parallel!
We use the Neck, Bend and Scale tools to manipulate our cubes.

In the interest of time we simply demonstrated part of a chair back. It's late and I'm lazy. But, the good news is that if you are using CB Model Pro, you've already proven that you're smart enough to figure out how to finish that chair.
