I was hoping someone could help me. I am trying to model a carpet roll, similar to the one shown here - http://www.contractorsflooringoutlet.net/carpet_roll_left.png
I know how to use the helix / spiral function and I can extrude the shape of the carpet roll fine. However I now want to add a pattern to the carpet, in my mind I want to 'unroll' the part, use cut extrude to create a pattern and then 'roll' the part back. What is the best way of achieving this?
