# 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
|
||
|
|
|
||
|
|
include <ellipse_extrude.scad>;
|
||
|
|
|

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