Spherical Spiral Plugin

Download SketchUp Plugin Spherical Spiral


This plugin draws a 3D spherical spiral that winds around the surface of a sphere, going from pole to pole.

It is Archimedean in the sense that, like the 2D Archimedean spiral, the windings are all an equal distance apart. For a spherical spiral that is not Archimedean, check out the loxodrome.


Spherical Spiral Dialog Box

This plugin is accessed from the Draw menu (Draw > Spherical Spiral). This will open a dialog box to enter the spherical spiral parameter values.

The more edges per revolution, the smoother the curve.

When you click OK, the spiral is created as a component, and the component placement tool is activated to position the spiral in the model.

The dialog box remembers the values between SketchUp sessions.
