      Here is another simple to use plugin for geometry creation. The spiral is a 3D curve that wraps around the surface of a sphere, going from pole to pole. Specifically, this is an Archimedean spherical spiral because, like the 2D Archimedean spiral, the turns are all the same distance apart.

      To activate, select Draw -> Spherical Spiral (Archimedes). Enter the parameters in the dialog box, and the spherical spiral is created as a component that you can place in the model.

      It looks better if you give the spiral curve some substance using a plugin like Tube Along Path.

      The Spherical Spiral is at: regularpolygon.org/plugins/spherical-spiral.php.

      Thanks

          They were drawing spirals on a torus, so this wouldn't really help, right? 😕

          But I was thinking, that would be another good plugin. One that draws a spiral on a torus. The spiral can revolve around two directions, the "big circle" and the "little circle." A simple plugin would allow you to enter the number of revolutions in each direction and then draw the spiral. 💭

            @Regular Polygon:
            Thank you for your efforts. These rubies you have done will be very useful.

            I take the slow, deliberate approach in my aimless wandering.
