Hello everyone:
I've been trying to do this on and off for about a year now and have not come up with a solution. I was hoping as my skills increased that I would come to a solution. I am hoping like with many things in Fusion there is a workaround.
The end result of this is a smooth 3d surface lofted so that it looks like an Iris leaf. I can make these flat without issue at this point. Unfortunately flower leaves also bend out in 3d and twist. Since flowers usually have more than one leaf I am trying to make a parametric component so that I can reuse the part, scale it up, etc. I could do this multiple times but it would be a real waste of potential reuse, plus it takes a few hours to make each one.
I have a 3d spline made of 2 CV splines and the intersection curve tool. This way it can be fully locked down. I have parameters to control how much it curls away from the Z axis in Y and X. It does not need to be super exact just locked down.
I tried lofting a "ribbon" flat surface with some twist to get a smooth change along the spline. Then I tried using surface disks made with patch to divide the 3d spline equally since pattern on path only works with objects. Then put a sketch on each of the leaf profile. This was attached to the ribbon to keep everything going around the plane and on the path. This works until I change the underlying spline.
I also tried as a test case (included) making 5 planes along path on the 3d spline and they all break as well once I change the underlying spline.
I would like the planes or the pattern on path disks to survive some mild updates. Which they do not. Is there a workaround for this?
I have also tried components along the path made by the spline. This way I did not have to redo all the sketches. That did not work as well.
I in the past also tried a "Ladder" structure in 2d with intersection and with in 3d with pentaprisms so that like three legged (or 4 legged) stools stacked up I could shorten one leg on each stool and then the whole thing would curl. Broke when I tried it in 3d.
I'm hoping there is indeed a workaround or something basic I am missing. Thank you all for your help.
