                Please write an AIDL program to generate a umbrella

Sure! Let's write an AIDL program to generate a simple 2D model of an umbrella. For simplicity, we'll create an umbrella with a solid canopy and a curved handle. We'll use circles and lines to construct the model.

We'll break down the design into three main parts:
1. Canopy (solid)
2. Handle (solid with a curved shape)
3. Ribs (as details in the form of engraved lines)

Here's the complete AIDL program:

```python
from AIDL import *

def umbrella(canopy_radius: float = 3*inches, handle_height: float = 4*inches, handle_radius: float = 0.25*inches):
    """
    Create a simple model of an umbrella with a curved handle and solid canopy.
    """

    # Define the structure of the umbrella
    umbrella = Solid()
    
    # Canopy
    canopy = Solid(shift=(0, handle_height))
    umbrella.canopy = canopy
    canopy.shape = Circle((0, 0), canopy_radius)
    
    # Handle
    handle = Solid()
    umbrella.handle = handle

    # Handle is represented as a line (shaft) with an arc at the bottom (curved part)
    handle.shaft = Line((0, 0), (0, handle_height - handle_radius))
    handle.curve = Arc((0, 0), 180, 0, handle_radius)
    
    # Ribs (engraved details on canopy)
    ribs = Drawing()
    canopy.ribs = ribs
    
    num_ribs = 8
    ribs.lines = []
    for i in range(num_ribs):
        angle_rad = 2 * pi / num_ribs * i
        rib_end_x = canopy_radius * cos(angle_rad)
        rib_end_y = canopy_radius * sin(angle_rad)
        ribs.lines.append(Line((0, 0), (rib_end_x, rib_end_y)))
        
    return umbrella

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

### Explanation:

1. **Canopy**:
    - A solid structure representing the umbrella canopy.
    - It's a circle with a user-defined radius.

2. **Handle**:
    - A solid structure representing the umbrella handle.
    - The handle is composed of a straight line (shaft) and a semi-circular arc (curve) at the bottom for the curved part of the handle.

3. **Ribs**:
    - Drawing lines as ribs on the canopy.
    - The ribs are created by drawing lines from the center of the canopy to the edge at equal angles.

The program uses a function `umbrella` with default parameters for the canopy radius, handle height, and handle radius. The geometry is defined within the function, and the model is created, solved, and rendered with the provided snippet.

If you have any specific features or further adjustments you'd like to make to the model, please let me know!
