How can I make pattern along the surface

I have a hole on the helix surface. How can I replicate other 13 holes along that helix surface?

Thank you

Use a pattern on path.  This image shows the basic idea, but the path needs to be defined in line with the hole(s):

Note: Attach  your Fusion .f3d file instead of a .step file if  you need further assistance.

I did that way. However, when I make more holes and drag them further. they become off! The holes don't stick to the surface of the helix at all. 😥

I also make 3d helix sketch, but still doesn't work. If I could attach a hole to the helix sketch, then use pattern path that could solve the problem, but how can I attach a circle sketch to the 3d helix sketch is another problem.

Can you share your Fusion file? Without that, we will to a large extent be shadow boxing.

Here's another method:
