I am new at Blender, I want to design a mesh of a single twisted yarn, which is the best strategy to design this mesh. Sorry if my question sounds dumb.

I am attaching the picture ![enter image description here enter image description here

I foud a tutorial in youtube: https://www.youtube.com/watch?v=cP1pY14fVC4&list=LLuORS2hOBqsUJEgE645iWDQ&index=2&t=1026s, however, I dont know how to merge the mesh.

EDIT Is this mesh true, I am going to use it for physical simulation

    $\begingroup$ you need to enable the Snap option (magnet icon) / vertex mode, (or press ctrl to enable the Snap while you move your mesh) and also the Auto Merge option, which, in 2.8, is in the 3D view N panel (top right) > Tools > Options, tell me if it works $\endgroup$

  • Create a 12 vertices circle.

enter image description here

  • Enable the Snap option (Vertex mode), or just press ctrl when you'll need it, enable the Auto-Merge option.

enter image description here

  • Duplicate your circle, with Snap and Auto-Merge it will snap and merge the vertices. Delete the inner vertices, bevel the 3 central vertices with a shiftctrlB.

enter image description here

  • Extrude up, create horizontal edge loops with ctrlR. To make sure you don't have flipped normals, press shiftctrlN. Back in Object mode, move the origin to the geometry.

enter image description here

  • Give your object a Simple Deform modifier, Angle 120°, Axis Z.

enter image description here

  • Give it an Array modifier, enable the Merge and First Last options.

enter image description here

  • Give it a Subdivision Surface modifier, and also smooth it: Object > Shade Smooth.

enter image description here

  • To make it follow a curve, give it a Curve modifier. Make sure that the curve's origin is at its beginning, put the object at the same point.

    $\begingroup$ I'm also on Mac, Auto-Merge should appear once in Edit mode, are you in Edit mode? $\endgroup$

    $\begingroup$ Plus, if you're not familiar yet with basic blender operations you should work on some beginners tutorials ;) $\endgroup$

    $\begingroup$ at 18:40 he uses the Proportional Editing option (little blue sphere icon) with the Linear setting, but the Simple Deform modifier is more precise $\endgroup$
