Reply to Bob,

OK, I was wrong. I just flattened a helix in IV6 that would be similar to the sides of your chute. Turned out to be just a parallelogram. I could not do the bottom though. I think you can flatten the helix if the face you want to flatten is concentric with the axis. This makes sense to me. If the face was perpindicular to the axis and you had more than one revolution, flattening would result in the object colliding with itself so this might be a built in limitation although I have not tried this in version 10.

Please reply if you find a solution.

Thanks,

Henry
