                Please write an AIDL program to generate a hot air balloon

Sure! Let's start by breaking down the components of the hot air balloon and how we can model it in AIDL. A simplified hot air balloon can be broken down into the following primary parts:

1. **Envelope**: The balloon part, which is typically a sphere or a rounded polygon when translated to 2D.
2. **Gondola**: The basket that hangs below the envelope.
3. **Cords**: Connecting elements between the envelope and the gondola.

### Step 1: Define the Structure Hierarchy

First, let's outline the structures and their hierarchical relationships.

```python
from AIDL import *

def hot_air_balloon(envelope_radius: float = 3*inches, gondola_width: float = 1*inch, gondola_height: float = 0.5*inch):
    """
    Model a simple 2D representation of a hot air balloon with an envelope,
    gondola, and connecting cords.
    """
    # Create the main structure for the hot air balloon
    balloon = Solid()
    
    # Create the envelope structure
    envelope = Solid()
    balloon.envelope = envelope
    
    # Create the gondola structure
    gondola = Solid(shift=(0, - (envelope_radius + gondola_height)))
    balloon.gondola = gondola
    
    # Create the cords structure which will connect the envelope and gondola
    cords = Solid(shift=(0, -envelope_radius / 2))
    balloon.cords = cords
    
    return balloon

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

### Step 2: Add Geometry to Each Structure

1. **Envelope** - A simple circle
2. **Gondola** - A rectangle representing the basket
3. **Cords** - Lines connecting the envelope to the gondola

Let's add these geometries.

```python
from AIDL import *

def hot_air_balloon(envelope_radius: float = 3*inches, gondola_width: float = 1*inch, gondola_height: float = 0.5*inch):
    """
    Model a simple 2D representation of a hot air balloon with an envelope,
    gondola, and connecting cords.
    """
    # Create the main structure for the hot air balloon
    balloon = Solid()
    
    # Create the envelope structure
    envelope = Solid()
    balloon.envelope = envelope
    envelope.body = Circle((0, 0), envelope_radius)
    
    # Create the gondola structure
    gondola = Solid(shift=(0, - (envelope_radius + gondola_height)))
    balloon.gondola = gondola
    gondola.body = Rectangle((0, 0), gondola_width, gondola_height)
    
    # Create the cords structure which will connect the envelope and gondola
    cords = Solid(shift=(0, -envelope_radius / 2))
    balloon.cords = cords
    cords.left_cord = Line((0, envelope_radius / 2), (-gondola_width / 2, -envelope_radius / 2))
    cords.right_cord = Line((0, envelope_radius / 2), (gondola_width / 2, -envelope_radius / 2))
    
    return balloon

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

### Step 3: Add Constraints

Ensure the cords are connecting the envelope and gondola properly and the geometries align correctly.

```python
from AIDL import *

def hot_air_balloon(envelope_radius: float = 3*inches, gondola_width: float = 1*inch, gondola_height: float = 0.5*inch):
    """
    Model a simple 2D representation of a hot air balloon with an envelope,
    gondola, and connecting cords.
    """
    # Create the main structure for the hot air balloon
    balloon = Solid()
    
    # Create the envelope structure
    envelope = Solid()
    balloon.envelope = envelope
    envelope.body = Circle((0, 0), envelope_radius)
    
    # Create the gondola structure
    gondola = Solid(shift=(0, - (envelope_radius + gondola_height)))
    balloon.gondola = gondola
    gondola.body = Rectangle((0, 0), gondola_width, gondola_height)
    
    # Create the cords structure which will connect the envelope and gondola
    cords = Solid(shift=(0, -envelope_radius / 2))
    balloon.cords = cords
    cords.left_cord = Line((0, envelope_radius / 2), (-gondola_width / 2, -envelope_radius / 2))
    cords.right_cord = Line((0, envelope_radius / 2), (gondola_width / 2, -envelope_radius / 2))
    
    # Add constraints to align cords correctly
    gondola.AddConstraint(Coincident(gondola.body.top_left, cords.left_cord.end))
    gondola.AddConstraint(Coincident(gondola.body.top_right, cords.right_cord.end))
    envelope.AddConstraint(Coincident(envelope.body.center, cords.left_cord.start))
    envelope.AddConstraint(Coincident(envelope.body.center, cords.right_cord.start))
    
    return balloon

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

This defines a basic hot air balloon model with an envelope, gondola, and connecting cords. You can further refine and add more details if needed, like making the gondola more ornate or adding more lines (cords) for structural support.

It looks like we have a `NonLocalConstraint` error, which means a constraint is referencing geometry not within the local scope of that particular structure. We need to ensure that all constraints are local to the structure they are defined on.

Let's rethink the way we are applying constraints and ensure that they are respecting the AIDL rules for constraints. Instead of directly referencing points from different structures, let's use more local relationships where possible. Here's a revised version of our program:

### Step 1: Define the Structure Hierarchy

First, let's outline the structures and their hierarchical relationships.

```python
from AIDL import *

def hot_air_balloon(envelope_radius: float = 3*inches, gondola_width: float = 1*inch, gondola_height: float = 0.5*inch):
    """
    Model a simple 2D representation of a hot air balloon with an envelope,
    gondola, and connecting cords.
    """
    # Create the main structure for the hot air balloon
    balloon = Solid()
    
    # Create the envelope structure
    envelope = Solid()
    balloon.envelope = envelope
    
    # Create the gondola structure
    gondola = Solid(shift=(0, -(envelope_radius + gondola_height)))
    balloon.gondola = gondola
    
    # Create the cords structure which will connect the envelope and gondola
    cords = Solid(shift=(0, -envelope_radius / 2))
    balloon.cords = cords
    
    return balloon

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

### Step 2: Add Geometry to Each Structure

1. **Envelope** - A simple circle
2. **Gondola** - A rectangle representing the basket
3. **Cords** - Lines connecting the envelope to the gondola

Let's add these geometries.

```python
from AIDL import *

def hot_air_balloon(envelope_radius: float = 3*inches, gondola_width: float = 1*inch, gondola_height: float = 0.5*inch):
    """
    Model a simple 2D representation of a hot air balloon with an envelope,
    gondola, and connecting cords.
    """
    # Create the main structure for the hot air balloon
    balloon = Solid()
    
    # Create the envelope structure
    envelope = Solid()
    balloon.envelope = envelope
    envelope.body = Circle((0, 0), envelope_radius)
    
    # Create the gondola structure
    gondola = Solid(shift=(0, -(envelope_radius + gondola_height)))
    balloon.gondola = gondola
    gondola.body = Rectangle((0, 0), gondola_width, gondola_height)
    
    # Create the cords structure which will connect the envelope and gondola
    cords = Solid(shift=(0, -envelope_radius / 2))
    balloon.cords = cords
    cords.left_cord = Line((0, envelope_radius / 2), (-gondola_width / 2, -envelope_radius / 2))
    cords.right_cord = Line((0, envelope_radius / 2), (gondola_width / 2, -envelope_radius / 2))
    
    return balloon

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

### Step 3: Add Constraints

Ensure the cords are connecting the envelope and gondola properly and the geometries align correctly.

```python
from AIDL import *

def hot_air_balloon(envelope_radius: float = 3*inches, gondola_width: float = 1*inch, gondola_height: float = 0.5*inch):
    """
    Model a simple 2D representation of a hot air balloon with an envelope,
    gondola, and connecting cords.
    """
    # Create the main structure for the hot air balloon
    balloon = Solid()
    
    # Create the envelope structure
    envelope = Solid()
    balloon.envelope = envelope
    envelope.body = Circle((0, 0), envelope_radius)
    
    # Create the gondola structure
    gondola = Solid(shift=(0, -(envelope_radius + gondola_height)))
    balloon.gondola = gondola
    gondola.body = Rectangle((0, 0), gondola_width, gondola_height)
    
    # Create the cords structure which will connect the envelope and gondola
    cords = Solid()
    balloon.cords = cords
    cords.left_cord = Line((0, envelope_radius), (-gondola_width / 2, -(envelope_radius + gondola_height)))
    cords.right_cord = Line((0, envelope_radius), (gondola_width / 2, -(envelope_radius + gondola_height)))
    
    # Add constraints to ensure cords connect envelope and gondola properly
    balloon.AddConstraint(Coincident(envelope.body.center, cords.left_cord.start))
    balloon.AddConstraint(Coincident(envelope.body.center, cords.right_cord.start))
    balloon.AddConstraint(Coincident(cords.left_cord.end, gondola.body.top_left))
    balloon.AddConstraint(Coincident(cords.right_cord.end, gondola.body.top_right))
    
    return balloon

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

This revised approach should prevent the `NonLocalConstraint` error by ensuring all constraints are local to the structure they're defined in. Let's see if this works for you.
