Bending a Tsplines to sit on a ring

I am trying to create a ring and I have drawn a few basic leaves using tsplines that I would like to sit on the ring. I drew the leaves on the XY Plane to make the shapes easier to create. Now I would like to get the leaves onto the ring with the symmetry line along the outer edge of the ring. I would prefer to do this and keep the tsplines capabilities still in place for fine tuning, but if that is not possible thats ok I can go back and make adjustments before bending. Any help on how to get the leaves onto the ring would be appreciated. I am new to Fusion, so if there is a different work flow that would make this easier please offer suggestions for a better process. Thank you.

I am not sure I understand your explanation of where the leaves are supposed to be located.

Can you move them manually with the move tool into the desired proximity and orientation?

@TrippyLighting Thanks for your response. In the image I have shown below you can see that I have moved the leaves to the general location. The orange leaf as you can see the edges of the leaf hit close to the symmetry line so about 1mm above and below the outside edge of the ring, but in the middle of the leaf since it was made on a flat plane is only above the surface approximately 0.2 mm. I can move each point to be in the ballpark, but it wont be exact and probably wont look good after I add more detail. If there is an easier way to bend the leaf to the ring that would be extremely helpful. I understand that this will lose symmetry which is not a problem. If there is not an easy tool for this process then my next thought was to try and create a cylinder and use the pull command, but not sure if that will work.

Thanks for the screenshot and model. In Fusion, you must do this manually by moving the vertices.
I would not do this in Fusion, but in Blender with the "Simple deform" modifier.

If that interests you, I can create a screencast of how that works.

@TrippyLighting I had not heard of Blender 3D, but it looks to be a free program so I can certainly get it to use this tool. Is Blender 3D the best tool for this task in total or just for the bending of that I need done? The reason I went to fusion is because they incorporated t-splines which I was familiar with when Rhino 3D supported their plugin and have drawn some jewelry before. I am learning Fusion 360 to draw my sisters wedding ring (first ring design and designing on the curve is giving me a fit) so it might be just as easy to learn Blender 3D. Thanks for your help.

@TrippyLighting Thank you for the video, that definitely helped. I will download blender and play around with it to see if I could use the the tool for the whole task or if I need to just bend the design in Blender and bring it back into Fusion 360. As you mentioned Fusion 360 does have some good tspline manipulation tools and it uses the same tools as the Rhino plugin used so it was a learning curve for Fusion, but a quicker curve for the form tools and topology as I have experience there. The current leaves that I have shown are pretty basic and will get more detail. At this point I was just trying to figure out how I was going to do the design, so I guess the question will be how much detail can I get with blender and can I learn it in a reasonable time frame. Either way this was very helpful, thank you.

a LOT more with blender

blender has a steep learning curve.  it is well worth taking the time to learn if you plan on doing this type of thing with any frequency.

@laughingcreek Thanks for the reply and thoughts. Good to know that Blender can create detailed models. This is intended to be a 1 time project just drawing up my sisters wedding ring for 3d print and then molding and casting, but you never know I might use it for some items in the future. I watched a few tutorials and did notice that it will be a steeper learning curve. I will probably stick to a minimal set of manipulation tools for the design and see if I can get by. Hopefully I can google questions and find premade tutorials and use their community forum for anything I get super stuck on. Wish me luck, and thanks for the help.
