I want to create object like this:

How can I achieve this?

    $\begingroup$ There is an addon for that: "add curve: extra objects". Once activated, Shift A/Curve/Add curve spirals, then choose spheric and tune the parameters in the operator panel $\endgroup$

  • $\begingroup$ @RayMairlot, should be a duplicate, finally!! So... I'll just add another way to do it, without the addon (even if I don't know if it is mathematically correct) $\endgroup$

1 Answer 1


An alternative way, just to add to the catalogue found by Prashant in another question:

  • Add a plane and keep only one segment
  • Make an inclination at 45° in front view
  • Subdivide a lot (around 100 times)

enter image description here

  • In front view, select one extremity
  • Set the proportional editing to enabled and to linear
  • Make a "blank" rotation (0°) to adjust the falloff

  • Then in top view

  • R to rotate
  • Rotate at the maximum possible value
  • Rotate again ShiftR to repeat the last operation

enter image description here

Finally, add a cast modifier and let it to sphere with a factor of 1:

enter image description here

Edit: FYI, that can be done with a single subdivided segment kept horizontal. Rotate with linear falloff and grab Z with spherical falloff.
