# bend_extrude

The purpose of `bend_extrude` is to replace `bend` when you have a 2D shape. `bend_extrude` is faster and doesn't produce jagged edges.

**Since:** 1.3.

## Parameters

- `size` : The size of a square which can contain the target shape.
- `thickness` : The thinkness used to extrude the shape.
- `angle` : The central angle of the arc shape. The radius of the arc is calculated automatically.
- `frags` : Number of fragments. The target shape will be cut into `frags` fragments and recombined into an arc object. The default value is 24.

## Examples

The containing square of the target shape should be laid down on the x-y plane. For example.

	x = 9.25;
	y = 9.55;

	%square(size = [x, y]);
	text("A");

Once you have the size of the containing square, you can use it as the `size` argument of the `bend_extrude` module.

	use <bend_extrude.scad>

	x = 9.25;
	y = 9.55;

	bend_extrude(size = [x, y], thickness = 1, angle = 270) 
		text("A");
