How to carve a hollow cylinder along the curved surface in Fusion 360 Let me start with a disclaimer: I'm new to 3D design, to design in general and specifically brand new to Fusion 360. This is my first project.

I started by creating a hollow cylinder, with the one end open and the other end closed. For example a hollow cylinder with the bottom closed and the top open.

I was able to create such hollow cylinder using the cylinder and shell tools.

Now, I wish to carve / engrave a pattern on the shell. I may want this carving to go all the way through the shell (practically making a hole the shape of my pattern); or,I may just want to engrave on part of the shell, but not cut all the way though.

My pattern is a sound wave. I have a 2D black and white image of this sound wave. I may want to carve it onto the curved shell, so that it curves around the cylinder. 

I hope my description is clear. Another way to describe what I'm looking for, is to imagine cutting the sound wave pattern though a 2D rectangle, and then curl this rectangle along its width into a cylinder.

How can I do something like that?
If you want it to be engraved, then sketch out the sound wave on the center plane. When you go to extrude, click "extrude from", and then click "from object". Click on the plane you want to extrude from, and then 2xtrude however for you would like to. Another way to do this would be to project the sketch onto the surface, and then extrude the projection.
