 ## Parameters
 
 - `points` : The list of `[x, y, z]` points of the polyline. The points are indexed from 0 to n-1.
-- `thickness` : The line thickness.
+- `diameter` : The line diameter. Default to 1.
 - `$fa`, `$fs`, `$fn` : Check [the sphere module](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Primitive_Solids#sphere) for more details.
