                Please write an AIDL program to generate a hot air balloon

Sure, let's break down the problem and consider the structural composition of a hot air balloon.

Here's how we can conceptualize the hot air balloon:
1. **Envelope**: The balloon part of the hot air balloon, which we can model as a semicircle with vertical lines radiating out from the center to represent seams.
2. **Basket**: The part where passengers stand, typically a rectangle.
3. **Cords**: Connecting lines between the basket and the envelope.

Let's proceed with the AIDL program:

```python
from AIDL import *

def hot_air_balloon(envelope_radius: float = 5*inches, basket_width: float = 2*inches, basket_height: float = 1*inches, cord_count: int = 6):
    """
    Creates a simplified model of a hot air balloon with an envelope represented by a semicircle,
    a basket as a rectangle, and cords connecting the basket to the envelope.
    """
    
    balloon = Solid()  # root structure for the balloon

    # Define the envelope (semicircle)
    envelope = Solid(shift=(0, envelope_radius + basket_height + 1*inches))
    envelope.top = Arc((0, 0), 0, 180, envelope_radius)
    envelope.left_side = Line(envelope.top.start, (0, -envelope_radius))
    envelope.right_side = Line(envelope.top.end, (0, -envelope_radius))
    
    # Add seams to the envelope
    seam_spacing = 180 / (cord_count + 1)  # evenly spaced seams
    envelope.seams = [Line((0, 0), (envelope_radius * cos(radians(seam_angle)), envelope_radius * sin(radians(seam_angle))))
                      for seam_angle in range(-90, 91, int(seam_spacing))]
    
    # Define the basket (rectangle)
    basket = Solid(shift=(0, 0))
    basket.body = Rectangle((0, -basket_height/2), basket_width, basket_height)

    # Define the cords (lines connecting basket to envelope)
    cords = Solid()
    cords.cords = [Line((basket_width * i / (cord_count - 1) - basket_width / 2, -basket_height), (envelope_radius * cos(radians(-90 + seam_spacing * i)), envelope_radius * sin(radians(-90 + seam_spacing * i))))
                   for i in range(cord_count)]
    
    # Attach the envelope, basket, and cords to the balloon
    balloon.envelope = envelope
    balloon.basket = basket
    balloon.cords = cords

    return balloon


with AIDL_2D:
    model = hot_air_balloon()
print(model.Solve())
model.Render()
```

### Explanation:

1. **Envelope**:
    - The `envelope` is modeled as a semicircle (top part) and lines connecting down to the bottom (left and right sides).
    - Seams are drawn as lines radiating from the center to the perimeter, spaced evenly.

2. **Basket**:
    - The `basket` is a simple rectangle centered at origin, shifted down vertically.

3. **Cords**:
    - The cords are lines connecting points on the top of the basket to points along the edge of the semicircle.

4. **Structure Tree**:
    - `balloon` is the root with `envelope`, `basket`, and `cords` as children.

You can run this code in the AIDL environment to see the resulting 2D CAD model of the hot air balloon. Let me know if any adjustments are needed or if there are additional features you'd like to add.
