- `shape_pts` : A list of points represent a shape. See the example below.
- `radius` : The circle radius.
- `angle` : Defaults to 360. Specifies the number of degrees to sweep, starting at the positive X axis. It also accepts a 2 element vector which defines the central angle. The first element of the vector is the beginning angle in degrees, and the second element is the ending angle.
- `twist` : The number of degrees of through which the shape is extruded.
- `twist` : The number of degrees of through which the shape is twisted.
- `scale` : Scales the 2D shape by this value over the length of the extrusion. Scale can be a scalar or a vector.
- `triangles` : `"SOLID"` (default), `"HOLLOW"` or user-defined indexes. See [polysections](https://openhome.cc/eGossip/OpenSCAD/lib2x-polysections.html) for details.
- `$fa`, `$fs`, `$fn` : Check [the circle module](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Using_the_2D_Subsystem#circle) for more details.
