                Please generate a 2D CAD file in OpenSCAD for lighthouse

Creating a lighthouse in a 2D CAD file using OpenSCAD involves using basic geometric shapes and transformations. Below is a simple example of how to build a basic 2D lighthouse profile.

```openscad
// This script generates a simple 2D profile of a lighthouse

module lighthouse() {
    difference() {
        // Main lighthouse body
        union() {
            // Lighthouse base
            cylinder(h=60, r1=20, r2=15, $fn=100, center=false);
            
            // Light room at the top
            translate([0, 0, 50])
            cylinder(h=15, r1=8, r2=8, $fn=100, center=false);
            
            // Top roof
            translate([0, 0, 65])
            cylinder(h=5, r1=10, r2=0, $fn=100, center=false);
        }
        
        // Hollow out the inside to make walls
        translate([0,0,1])
        cylinder(h=59, r1=18, r2=13, $fn=100, center=false);
        
        // Hollow out the light room
        translate([0, 0, 51])
        cylinder(h=13, r1=6, $fn=100, center=false);
    }
}

// Project a 2D profile of the lighthouse
projection(cut = true)
    lighthouse();
```

How to use this code:

1. Open OpenSCAD.
2. Copy and paste the script into the OpenSCAD editor.
3. Press F5 to preview the lighthouse in 2D.
4. You can tweak the parameters as needed.

This code uses simple shapes to create a basic lighthouse structure. The `cylinder()` function constructs the conical and cylindrical sections of the lighthouse, while the `difference()` function is used to hollow out parts of it, showing how you might create inner "walls" and hollow sections for more realistic architectural features.

Feel free to modify the sizes and proportions to better fit your vision of a lighthouse!
