I've recently found myself unable to perform a seemingly simple action in Blender while creating my model. I want to create a "tube-like" edge where 2 of the parts connect together, but nothing I've tried has worked, since extruding the edge results in a plane that I can't scale properly. I'm unsure of what to do, as I'm quite new to Blender and don't fully understand what I'm doing. Explaining what I want to achieve seems a bit hard, so I've added some images! I'd really appreciate some help!

What my reference is, you can see the circular edge

    $\begingroup$ I added more images, I'm trying to create the bump that I've circled in red, but have little clue how to. I just need it do go along the top edges of the model, just like in the image. The same bump can be seen around the window. $\endgroup$

  • $\begingroup$ I would take the edge in question, duplicate it into an object that I convert from Mesh to a Curve, and have a cylinder use the Curve modifier. See my Answer below. $\endgroup$

Here is one example:

enter image description here

I started with a cube where I removed the top face and Beveled to look similar to your target shape. I then selected non-Manifold edges (or you can select these manually), 'D' (Duplicate), 'P' Separate Selection (into a new object 'Cube.001'),

enter image description here

I then converted the Cube.001 into a curve that will bend a new mesh:

enter image description here

Then I added a cylinder and subdivided only the vertical edges to make sure it had sufficient edges to bend along the curve,

enter image description here

and then used the Curve modifier to fit it. (you may have to adjust the axis of conformance, and move the cylinder or Object :: Apply :: Location):

enter image description here

My example:

You can add the Subdivision Surface modifier to smooth the outcome.
