I am failing on a embarrassing challenge. I am trying to create an actually pretty simple form, but I cant finish my work without distortion on my mesh.

enter image description here

This is the object I am working on.

So far I tried different strategies, but I have always the same issue:

As you can see, the Boolean modifier and all my other attempts failed.

The problem is the overlapping mesh obviously, but I don't know how to fix it. My best attempt so far was to make the whole object from only 1 curve:

But then my Circle looks a not really symmetrically. And if you look closely enough you can still see a little shadow/distortion on the point where the curve hits herself.

Is there a common known workflow or something to help me finishing my project?

  • $\begingroup$ do you need to do it with a curve or can it be made with mesh? $\endgroup$ – moonboots Apr 9 '19 at 16:33

As you're talking about booleans it looks like you're open to do it with mesh (rather than only curve), so here is a solution:

  • Create a torus (Major Segments: 24/Minor Segments: 8).
  • Duplicate one of its circle, make it another object, extrude on the Z axis.
  • Boolean the 2 objects.
  • In Top Ortho view cut in half with the knife, then mirror the whole object.
  • Use the knife to add some topology: K to activate, Z to cut through, C to cut orthogonally.
  • Give your object a Subsurf and Shade Smooth to test the result.
  • Use the same technic and also the Spin tool for the top of the object.

  • $\begingroup$ Thank you mate, this works fine. I still got some distortion in my mesh but it looks so much better than before :D $\endgroup$ – Forrest Apr 15 '19 at 12:18
  • $\begingroup$ oh ok great I was not sure about where was your problem... yes I know it's not perfect, maybe with a higher subdivision (when you create your torus) you could have better result $\endgroup$ – moonboots Apr 15 '19 at 12:42
