shape_ellipse


Returns shape points of an ellipse. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.

Parameters

  • axes : 2 element vector [x, y] where x is the semi-major axis and y is the semi-minor axis.
  • $fa, $fs, $fn : The shape created by this function can be viewd as resize([x, y]) circle(r = x) (but not the real implementation inside the module) so you can use these global variables to control it. Check the circle module for more details.

Examples

include <shape_ellipse.scad>;

polygon(
    shape_ellipse([40, 20])
);
