Regular rib pattern on irregular curved surface body

[johannes4YVX2]

Hi,
I am trying to replicate this style of ribs on an organic, irregular curved body. The rib profiles should follow the body and the profiles should not be distorted, just the spacing between the ribs should change.

Emboss works for a few ribs, but quickly breaks. I assume there is a way to wrap the body in paths and sweep along this paths, but I have no idea how to do it.
Thanks for the help!

This was done with T-Splines, so if not parametric. Does that interest you?

Extruding a profile in Form mode is the way I do it right now (I assume this is what you suggest). But this method is also distorting the ribs. I want the profile of the ribs unchanged, just following the contour of the body.

One way to do it is to create a T-spline body with the same amount of faces as there are ribs and then sweep every profile along the edge. But this is very laborious. I am hoping for a simpler solution.

Hi,

I have not tried this particular method but would your T-Splines method work if you selected one of

them and then created a Circular Pattern? They would then be evenly spaced around the perimeter

and you might not have to create each individual T-Spline.

Just a thought. I am sure one of the Gurus will have a solution probably better than mine.

Cheers

I did not use a sweep when modeling this. It will take at least an hour from the time of this post for the HD and 4K versions screencast to process on youtube.

That is geometrically not possible!

Here is my idea for a workflow if I understand your intent with the design. Only vertical ribs?

Inner cutout of shape is a downscale of outer surface.

There are some faces that are not correct in the file but will depend on the base shape you use.

I have the solution for this task, if you are still looking for it.

Thanks, Kristian!
As with most of my Fusion questions, I found the solution in one of your videos. 😄
I also want to take this opportunity to thank you for all your inspiring content, your videos are my single most important resource for improving my Fusion skills. I especially enjoy your tutorials on complex patterns, as that’s an area I consistently find challenging.

Greetings from Salzburg,
