Alibre Design - Modeling with a Twist

Thanks for this video. I know this is an older post, but this video helps me understand how to get closer to a design I'm working on. I am an Alibre newbie and am still getting my head around the tools. I'm trying to design a shelf, eventually to be carved on a CNC in pieces, that would be essentially a flat bar like you show, with 1/2 twist, but with one end lower than the other. So, rather than the two ends finishing in the same plane, one would finish perhaps 4 inches below the other. This would require the helix to be modified so that it curved down over an S-shaped path. How would one go about doing this? Is it possible with Alibre Atom or would Alibre Design be required? Thank you.

So, something like this:

This should be possible in Atom 3D by creating the twist as the first feature. Then create sketch for a Sweep at either end and project the end face of the twist into a profile sketch. Then create the sweep. Duplicate for the other end with another sweep. It will take a bit of fudging of the twist length to get the correct height of the completed part.
I'll create a short video to show the steps and post it later.
