ellipse_extrude

Extrudes a 2D object along the path of an ellipse from 0 to 180 degrees. The semi-major axis is not necessary because it's eliminated while calculating.

Parameters

semi_minor_axis : The semi-minor axis of the ellipse.
height : The extruded height. It defaults to semi_minor_axis if ignored. The height should not greater than semi_minor_axis. If it's greater than semi_minor_axis, the module will use semi_minor_axis.
center, convexity, twist, slices: The same as respective parameters of linear_extrude.

Examples

use <ellipse_extrude.scad>

semi_minor_axis = 5;
 
ellipse_extrude(semi_minor_axis) 
    circle(semi_minor_axis * 2);

use <ellipse_extrude.scad>

semi_minor_axis = 5;
 
ellipse_extrude(semi_minor_axis, height = 4.5) 
    text("A", valign = "center", halign = "center");

use <ellipse_extrude.scad>

semi_minor_axis = 5;
 
ellipse_extrude(semi_minor_axis) 
    text("♥", size = 40, valign = "center", halign = "center");
	
mirror([0, 0, 1]) 
ellipse_extrude(semi_minor_axis) 
    text("♥", size = 40, valign = "center", halign = "center");

use <ellipse_extrude.scad>

semi_minor_axis = 10;
 
ellipse_extrude(semi_minor_axis, twist = 30, slices = 10) 
    text("♥", size = 40, valign = "center", halign = "center");
