I have a straight line of vertices and I don't know how to make them be arranged in a circular shape such as the top part of a dome.

Can anybody help me?

  • $\begingroup$ do you want to bake just one line of vertices round? Or do you want to take a flat edge, and bridge the edge in to a round edge? $\endgroup$

  • $\begingroup$ Well, either way would be good. I just need to create a semi-circular shape. $\endgroup$

If you don't mind not using the original vertices, I would add a circle (ShiftA >Add circle) in edit mode, so that it's added straight into the current object.

If you want to keep the existing verts, you could try using the To sphere operator (AltShiftS), or the circle operator in the bundled loop tools addon (you will have to enable in User prefs > Addons).

enter image description here

In the above example I first rotated one of the end verts with proportional editing enabled (O), to give it a semi-circular shape. This makes it easier for the circle operator

    $\begingroup$ @Ben good point; in that situation you can put the 3D cursor in the actual center of the sphere (e.g. by selecting two opposing vertices and snapping the cursor to selected (shift+S)), then set the cursor as pivot (numpad .). To sphere at least will then be centered as expected, I'm not sure about looptools (and am currently on mobile, so I can't test atm) $\endgroup$

  • $\begingroup$ I will give it a go, if that works out, it would really sweeten my day! $\endgroup$

  • $\begingroup$ Loop Tools does not seem to give a hoot, but To Sphere works just as advertised! $\endgroup$
