Need Help Lofting/Sweeping a Complex Profile

[MDGroup]

I can visualize it in my head, but can't figure out how to get make it in the model.

I have a coiled rectangular profile.
In the center, I need it to twist and curve so it exits pointing downward with a square profile.

I need it to have a nice smooth transition maintaining the same minimum cross section area in the center.

My first thought is a loft, but it really messes up the profile, and deforms into a really akward shape. (Maybe just need to add some guide curves on each corner, but can't figure out how to create the nice smooth sweep I need.


Attached is an image of the loft, which is the basic idea I am looking for, but needs to be a lot smoother.
Also the SW file if any one wants to take a shot at it.

Thanks in advance.

SW file.

Feel free to change the orientation angle of the outlet if it makes it any easier / cleaner.

Thanks.

Have you looked at making a projected Curve?

Here is an example and there are several more videos showing a projected curve.

1. my first thought is to get the outside modeled, and then use a shell command to hollow out the inside and maintain a constant wall thickness.

2. my second thought is how will you fabricate this part?
