First off, I'm pretty new to blender, so I apologise if this is a basic problem/question.

I'm trying to create detail on a surface, and the most obvious way I can think of is to create a half cylinder and shrinkwrap it onto the surface. But I guess this only really works for planar type objects?

What's happening is that the cylinder is following the target surface properly, but it's totally squished flat onto the surface. I want to preserve the cylinder as it wraps over the surface.

Here's what I'm trying to do, I hope it explains it better than I can describe.

Target Object Surface: Target

The effect of the Shrink Wrap: Shrink

What I'm trying to emulate: Emulate

So the question is, is there a way to get shrinkwrap to do what I want, or is there a better way altogether?

    $\begingroup$ do you mean that you want to bend a pipe? maybe use a Curve modifier? $\endgroup$

  • $\begingroup$ @moonboots not the pipe, but the ribs on the muffler. Sorry, the first image I chose wasn't great $\endgroup$

  • $\begingroup$ don't create a new object, create edge loops on your object and extrude $\endgroup$

Rather than creating a new object, you could use your current object, create some edge loops:

Bevel them:

Only keep a part selected:

Press AltE to Extrude Faces Along Normals:

Here is what it gives when you give your object a Subdivision Surface modifier (put additional edge loops if you want to sharpen the edges):
