These data are especially valuable in establishing possible correlations from the various parameters (either torsion angles or the often-preferred helicoid parameters) that describe the structures. A cone-shaped minaret with outside spiral ramp, or a helicoid, can be modified to serve as examples where a gradient flow converges to a limit cycle. The nuclear whorls number at least 2, forming a depressed helicoid spire, which is obliquely, almost one-half immersed in the first of the succeeding turns.

Conversely, a plane can be turned into a helicoid by choosing a line, or "axis", on the plane, then twisting the plane around that axis.

These tropocollagen molecules are intercalated with the mineral phase (hydroxyapatite, a calcium phosphate) forming fibrils that curl into helicoids of alternating directions.

The tube strongly simulates the shell of certain serpulid sea worms or helicoid land snails and contain no less than 75% calcium carbonate.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The helicoid is also a ruled surface (and a right conoid), meaning that it is a trace of a line.

Other examples are a conical surface with elliptical directrix, the right conoid, the helicoid, and the tangent developable of a smooth curve in space.
