# OpenSCAD Quarter Circle/Torus
This repository hosts an OpenSCAD script with a couple of modules for drawing
quarter circles and tori.
The recommended installation method is to add this repository as a submodule in
your repository and pull in the script with this line:
```openscad
use
```
The documentation for the available modules follows.
## `quarter_circle`
Parameters:
- `side`: the side of the enclosing square (default `10`)
- `quadrant`: the quadrant of the circle to draw (default `0`)
- `0`: top left quarter circle
- `1`: bottom left quarter circle
- `2`: bottom right quarter circle
- `3`: top right quarter circle
- `$fn` (facet number): built-in OpenSCAD variable for smoothing the round edge
```openscad
linear_extrude(height = 1)
quarter_circle(quadrant = 0, $fn = 100);
```
```openscad
linear_extrude(height = 1)
quarter_circle(quadrant = 1, $fn = 100);
```
```openscad
linear_extrude(height = 1)
quarter_circle(quadrant = 2, $fn = 100);
```
```openscad
linear_extrude(height = 1)
quarter_circle(quadrant = 3, $fn = 100);
```
## `inverted_quarter_circle`
Parameters:
- `side`: the side of the enclosing square (default `10`)
- `quadrant`: the inverted quarter of the circle to draw (default `0`)
- `0`: top left inverted quarter circle
- `1`: bottom left inverted quarter circle
- `2`: bottom right inverted quarter circle
- `3`: top right inverted quarter circle
- `$fn` (facet number): built-in OpenSCAD variable for smoothing the round edge
```openscad
linear_extrude(height = 1)
inverted_quarter_circle(quadrant = 0, $fn = 100);
```
```openscad
linear_extrude(height = 1)
inverted_quarter_circle(quadrant = 1, $fn = 100);
```
```openscad
linear_extrude(height = 1)
inverted_quarter_circle(quadrant = 2, $fn = 100);
```
```openscad
linear_extrude(height = 1)
inverted_quarter_circle(quadrant = 3, $fn = 100);
```
## `quarter_torus`
Parameters:
- `angle`: the extrusion angle (0-360)
- `radius`: the radius of the torus hole
- `side`: the bounding square side of the looped quarter circle making the torus
(default `10`)
- `quadrant`: the orientation and type of the slope of the hole (0-3, difficult
to explain - just try it)
- `$fn` (facet number): built-in OpenSCAD variable for smoothing the round edge
```openscad
quarter_torus(quadrant = 0, $fn = 100);
```
```openscad
quarter_torus(quadrant = 1, $fn = 100);
```
```openscad
quarter_torus(quadrant = 2, $fn = 100);
```
```openscad
quarter_torus(quadrant = 3, $fn = 100);
```
## `inverted_quarter_torus`
Parameters:
- `angle`: the extrusion angle (0-360)
- `radius`: the radius of the inverted torus hole
- `side`: the bounding square side of the looped inverted quarter circle making
the torus (default `10`)
- `quadrant`: the orientation and type of the slope of the hole (0-3, difficult
to explain - just try it)
- `$fn` (facet number): built-in OpenSCAD variable for smoothing the round edge
```openscad
inverted_quarter_torus(quadrant = 0, $fn = 100);
```
```openscad
inverted_quarter_torus(quadrant = 1, $fn = 100);
```
```openscad
inverted_quarter_torus(quadrant = 2, $fn = 100);
```
```openscad
inverted_quarter_torus(quadrant = 3, $fn = 100);
```
