                Please generate a 2D CAD file in OpenSCAD for butterfly

Let's start by creating a simple 2D butterfly shape in OpenSCAD. The script will utilize basic shapes like circles and polygons to approximate a butterfly. Here is a sample OpenSCAD script to generate a 2D butterfly:

```openscad
// Butterfly parameters
wing_width = 30;
wing_height = 50;
body_width = 10;
body_height = 60;

// Function to draw a wing
module wing() {
    // Draw outer wing using circle and polygon for more control over shape
    difference() {
        union() {
            translate([-wing_width / 2, 0]) circle(wing_width, $fn=30);
            scale([1, 1.5]) polygon(points=[[0,0], [wing_width,0], [wing_width/2, wing_height]]);
        }
        // Cut out inner part to shape it more like a butterfly wing
        translate([-wing_width / 4, 0]) circle(wing_width / 2, $fn=30);
    }
}

// Draw butterfly
module butterfly() {
    // Left wing
    translate([-wing_width, wing_height / 2])
        rotate([0, 0, 30])
        wing();

    // Right wing
    translate([wing_width, wing_height / 2])
        rotate([0, 0, -30])
        wing();

    // Body
    translate([-body_width / 2, -body_height / 2])
        square([body_width, body_height]);
}

// Call the butterfly module to display the butterfly
butterfly();
```

In this script:

- The `wing()` module creates an outer circular wing and uses a polygon to control its shape further.
- The `butterfly()` module positions and rotates the wings to form a butterfly shape.
- The body is represented by a simple rectangle.

Copy and paste this script into OpenSCAD and render it to visualize the 2D butterfly. You can tweak the parameters and shapes to better fit your design requirements. This gives you a starting point for more complex modifications.
