Anybody have any idea how to model this twisted pendant ?
To laser cut this pendant, each wood stick should be in a single plane.
Thanks a lot.

Ok John.
First time in the forum, sorry about it.
I'd expect an "Extrude Sweep" with "Twist along path" to be somewhere in your feature tree.
I did a loft with 3 sketch doing the twist.
Look a little bit close to what i want.
But, how will i split this thing to get the wood sticks ?
How about lofting a cut which twists the other way?
Got something like this.
Your 1-piece solid body is a good start. Is it also hollow?
I don't think that the cuts are twisted. See image. Vertical pieces directly in front of the light bulb show that they are vertical flat pieces.
Use a sketch like this on top plane, and cut through all checking the Flip Side to Cut box. Result: flat pieces to cut, pattern, and assemble.
The piece tying these slats together, near the top and bottom, is less clear. Maybe that's just another flat piece defined by intersections and offset from inner edges of the vertical bodies.
Its worked.
But the cross section in each stick in not constant, and is not suitable for manufacture.
Good progress so far. I'm not certain of this suggestion, but I hope it is a useful idea. Try this with one rib, and see if it is worth applying to all, either individually or as a whole. (I think individual is tedious but will surely work easier as simpler)
Use what you have as a framework only. Create new Sketch on nearly radial flat face. Select the outer edge of this rib, and Convert Entities. Use that sketch as your Path for a new Sweep, constraining your Profile not to twist along path. Perhaps an opposite inner edge would also be needed for a second guide curve. DON'T Merge result. Suppress the Solid Body rib from before, but not its features which created and parented your Sweep Path. Intended result: Consistent rectangular cross-section of new rib pieces.
Alternative: Instead of cutting as suggested before (rollback or delete the cut, maybe keep the sketch), just create radial planes = to number needed. Again with Sketch upon radial planes, create a Curves -> Split Line -> Intersection while selecting radial plane and outer surface. Again, use that as a sweep, but if the radial planes are truly radial, be sure to center the short face of the profile along the path instead of a corner. In this alternative, you've kept the solid form as one body which becomes a reference and then is similarly suppressed as a body but not a feature. It's a lot less bodies to manage that way.
Maybe I'm rambling.
awesome ! do you mind to share your part here
Ok....

I am follow this approach.
I will be a little cheaper to manufacture.
I still need to add 3 extras supports to holding the vertical "sticks", one on the bottom, one on the top, one in the middle.
And then design the jigs.
