I want to draw lines on the surface of an object and then connect them. I am doing this by drawing curves. When I connect the curves the connection between them has sharp edges, which I don't want. I need something as the draw tubes in this video: https://www.youtube.com/watch?v=SgkzU8vhCj0. How do I create rounded edges (indicated in red) as in following figure: enter image description here

    $\begingroup$ You may have your handles type set as vector. Try selecting the points you want (or the whole curve) then press V and select Aligned. $\endgroup$ Aug 12, 2021 at 16:22
  • $\begingroup$ @ChristopherBennett this does not lead to the edges being rounded $\endgroup$
