human: Generate a python script that works in Blender 3.4.1 that creates 200 curves that overlap and combine to look like a road network.

assistant: Here's a Python script that works in Blender 3.4.1 to create 200 curves that overlap and combine to look like a road network:

```python
import bpy
import random

# Set the number of curves to create
num_curves = 200

# Create a new collection to hold the curves
collection = bpy.data.collections.new("Road Network")
bpy.context.scene.collection.children.link(collection)

# Loop through and create the curves
for i in range(num_curves):
    # Create a new curve object
    curve = bpy.data.curves.new("Curve", "CURVE")
    curve.dimensions = '3D'
    curve.resolution_u = 2
    
    # Create a new spline and set the control points
    spline = curve.splines.new('NURBS')
    spline.points.add(3)
    spline.points[0].co = (0, 0, 0, 1)
    spline.points[1].co = (random.uniform(-5, 5), random.uniform(-5, 5), random.uniform(0, 5), 1)
    spline.points[2].co = (random.uniform(-10, 10), random.uniform(-10, 10), random.uniform(5, 10), 1)
    spline.points[3].co = (random.uniform(-20, 20), random.uniform(-20, 20), random.uniform(10, 20), 1)
    
    # Set the curve object's data and add it to the collection
    curve_obj = bpy.data.objects.new("Curve_" + str(i), curve)
    collection.objects.link(curve_obj)
    
# Combine the curves into one object using the Boolean modifier
bool_mod = collection.objects[0].modifiers.new(type="BOOLEAN", name="Combine")
bool_mod.operation = 'UNION'
for i in range(1, num_curves):
    bool_mod.object = collection.objects[i]
    bpy.context.view_layer.objects.active = collection.objects[i-1]
    bpy.ops.object.modifier_apply(modifier="Combine")
    
# Remove the original curve objects
for obj in collection.objects:
    if obj.type == 'CURVE':
        bpy.data.objects.remove(obj, do_unlink=True)
```

This script creates 200 curves with random control points and combines them into a single object using the Boolean modifier. The resulting object looks like a network of roads. You can adjust the parameters of the random.uniform() function calls to change the appearance of the road network.

human: Is it possible to have the curves generated be Bezier curves? How would the above code change, if at all?

assistant: Yes, it's possible to generate Bezier curves instead of NURBS curves. Here's the modified code:

```python
import bpy
import random

# Set the number of curves to create
num_curves = 200

# Create a new collection to hold the curves
collection = bpy.data.collections.new("Road Network")
bpy.context.scene.collection.children.link(collection)

# Loop through and create the curves
for i in range(num_curves):
    # Create a new curve object
    curve = bpy.data.curves.new("Curve", "CURVE")
    curve.dimensions = '3D'
    curve.resolution_u = 2
    
    # Create a new spline and set the control points
    spline = curve.splines.new('BEZIER')
    spline.bezier_points.add(3)
    spline.bezier_points[0].co = (0, 0, 0)
    spline.bezier_points[1].co = (random.uniform(-5, 5), random.uniform(-5, 5), random.uniform(0, 5))
    spline.bezier_points[2].co = (random.uniform(-10, 10), random.uniform(-10, 10), random.uniform(5, 10))
    spline.bezier_points[3].co = (random.uniform(-20, 20), random.uniform(-20, 20), random.uniform(10, 20))
    
    # Set the curve object's data and add it to the collection
    curve_obj = bpy.data.objects.new("Curve_" + str(i), curve)
    collection.objects.link(curve_obj)
    
# Combine the curves into one object using the Boolean modifier
bool_mod = collection.objects[0].modifiers.new(type="BOOLEAN", name="Combine")
bool_mod.operation = 'UNION'
for i in range(1, num_curves):
    bool_mod.object = collection.objects[i]
    bpy.context.view_layer.objects.active = collection.objects[i-1]
    bpy.ops.object.modifier_apply(modifier="Combine")
    
# Remove the original curve objects
for obj in collection.objects:
    if obj.type == 'CURVE':
        bpy.data.objects.remove(obj, do_unlink=True)
```

The main difference is that we're now creating Bezier curves instead of NURBS curves. We're also using `spline.bezier_points` instead of `spline.points` to set the control points. Other than that, the code is very similar to the original version.
