Perforate a cylindrical shape

I have this model I'm working on and I'd like to perforate the dark blue part with a pattern of hexagons. I know you can't user the pattern feature on curves. And I'm struggling to find a way to project the shape and repeat, because of the nature of the curved part. Anybody have a good suggestion?
Thanks

Hey Mark. Here is a method you might be able to use to perforate your part. Playing around with the shape (shapes?) in sketch 1 might get what you want. The Circular Pattern feature allows the removal of pattern instances should the pattern fall upon an edge of the part, which I assume would be undesirable.
Beyond using Onshape's native tools. Evan Reese created a custom feature you might be able to use. Check out this post for a discussion, link to the feature script and a video of using the feature script. - Scotty

You could do it as a sheet metal part and pattern the holes in a sketch in the flat pattern.

Evan Reese's custom feature is excellent! Thank you.
So I have a slightly different suggestion: use the native wrap feature, along with a bit of work.
Basically, do this: create a cylinder the same diameter and height as your shape. Create an appropriate sketch with the holes you want to create, and use the native Wrap feature to project that onto the cylinder, and create new solids. You can then simply use those new solid parts to remove portions of your custom shape.
