code pyautocad draw tree

Creating a tree using PyAutoCAD involves using the `pyautocad` module to programmatically draw tree-like structures in AutoCAD. Since AutoCAD is primarily a tool for drawing geometric shapes and not organic structures, the representation will be stylized and abstract. Here's a basic example of how you might use PyAutoCAD to draw a simplified tree comprising a trunk and branches.

First, make sure you have PyAutoCAD installed. You can install it via pip if you haven't already:

```bash
pip install pyautocad
```

Now, here's a Python script that uses PyAutoCAD to draw a simple tree:

```python
from pyautocad import Autocad, APoint

def draw_tree(base_point, trunk_height=100, trunk_width=10, num_branches=3, branch_length=50, branch_angle=45):
    acad = Autocad(create_if_not_exists=True)

    # Draw the trunk
    trunk_start = base_point
    trunk_end = APoint(trunk_start.x, trunk_start.y + trunk_height)
    acad.model.AddLine(trunk_start, trunk_end)

    # Calculate branch starting points
    branch_start_y = [trunk_start.y + (trunk_height / (num_branches + 1)) * (i + 1) for i in range(num_branches)]

    for y in branch_start_y:
        branch_start = APoint(trunk_start.x, y)

        # Calculate end points for left and right branches
        left_branch_end = APoint(branch_start.x - branch_length, branch_start.y + branch_length * (branch_angle / 90))
        right_branch_end = APoint(branch_start.x + branch_length, branch_start.y + branch_length * (branch_angle / 90))

        # Draw branches
        acad.model.AddLine(branch_start, left_branch_end)
        acad.model.AddLine(branch_start, right_branch_end)

# Define where the base of the tree will be
base_point = APoint(0, 0)

# Draw a tree
draw_tree(base_point=base_point)
```

### Explanation:
- **Trunk**: The trunk is represented by a vertical line, starting from the base point and going upwards.
- **Branches**: Branches are lines starting from points along the trunk, angled outwards and upwards. The number of branches and their angles can be adjusted via function parameters.
- **APoint**: Used to define points in AutoCAD's coordinate system.

#### Important Notes:
- **Coordinate System**: AutoCAD uses its own coordinate system, where `(0, 0)` is usually the origin.
- **Active Document**: PyAutoCAD interacts with the currently active AutoCAD document. Ensure AutoCAD is open and there's an active drawing.
- **Permissions**: Ensure you have the necessary permissions and software configuration to run scripts that interact with AutoCAD.

This script gives a basic framework for drawing a tree. For more complex and organically shaped trees, consider using more advanced algorithms or libraries designed for procedural generation of natural elements.

code pyautocad draw tree

Drawing a tree using PyAutoCAD involves automating the creation of several geometric shapes that represent parts of a tree (e.g., trunk, branches, and leaves). PyAutoCAD is a Python library that enables integration with AutoCAD, allowing for automation of tasks. However, creating detailed tree graphics using basic geometric shapes may not be straightforward, as it requires a careful combination of lines, arcs, and perhaps even solid shapes.

Below is an example that demonstrates how to draw a simplified representation of a tree. Note that this serves as a basic guideline and you might want to enhance it for more realistic drawings.

Firstly, ensure PyAutoCAD is installed:
```bash
pip install pyautocad
```

The following Python script provides a simple illustration of what drawing a tree could look like with PyAutoCAD:

```python
from pyautocad import Autocad, APoint

# Initialize AutoCAD
acad = Autocad()

# Parameters for the tree
trunk_base = APoint(0, 0)
trunk_height = 50
trunk_width = 10

canopy_center = APoint(0, trunk_height)
canopy_radius = 30

# Draw the tree trunk as a rectangle (or polyline as an alternative)
trunk_points = [
    APoint(-trunk_width / 2, 0),                # Bottom-left
    APoint(trunk_width / 2, 0),                 # Bottom-right
    APoint(trunk_width / 2, trunk_height),      # Top-right
    APoint(-trunk_width / 2, trunk_height),     # Top-left
    APoint(-trunk_width / 2, 0)                 # Bottom-left to close the polyline
]
acad.model.AddPolyline(trunk_points)

# Draw the canopy as a circle
acad.model.AddCircle(canopy_center, canopy_radius)

# Optional: Draw branches (lines extending from the top of the trunk)
branch_length = 20
branches = [
    (APoint(0, trunk_height), APoint(-branch_length, trunk_height + branch_length)),  # Left branch
    (APoint(0, trunk_height), APoint(branch_length, trunk_height + branch_length))   # Right branch
]

for start_point, end_point in branches:
    acad.model.AddLine(start_point, end_point)

print("Tree successfully drawn in AutoCAD.")
```

### Key Points:
- **Trunk**: Using a polyline to represent the trunk. You could also use `AddRectangle` if preferred.
- **Canopy**: Represented as a circle; you may want to use more circles or arcs for more realism.
- **Branches**: Optional lines can be added for branches.

### Considerations:
- **Units and Scale**: Make sure the units and scale match your existing drawing or preferences.
- **Realism**: For more realistic trees, consider using blocks or more advanced shapes, possibly extracting or referencing them from existing tree files.
- Extend the script to dynamically place the tree in different locations or adjust sizes based on parameters.
  
This example is a basic starting point and could be expanded with more features as needed, possibly incorporating loops or iterative designs for complex structures such as fractal-like branching.

code pyautocad draw tree

Certainly! To draw a simple tree-like diagram in AutoCAD using Python, you can use the `pyautocad` library to interact with AutoCAD directly. Here's an example script that draws a tree shape using lines:

First, make sure you have the `pyautocad` library installed. You can install it using pip if you haven't done so:

```bash
pip install pyautocad
```

Then, you can use the following script as an example to draw a tree:

```python
from pyautocad import Autocad, APoint

# Initialize AutoCAD
acad = Autocad(create_if_not_exists=True)
acad.prompt("Hello! Automation begins...\n")

# Function to draw a line given start and end coordinates
def draw_line(start, end):
    acad.model.AddLine(APoint(*start), APoint(*end))

# Function to draw a simple tree structure
def draw_tree(trunk_bottom, trunk_top, branch_length):
    # Draw trunk
    draw_line(trunk_bottom, trunk_top)

    # Calculate branch positions on top of the trunk
    center_x, trunk_top_y = trunk_top
    left_branch_top = (center_x - branch_length, trunk_top_y + branch_length)
    right_branch_top = (center_x + branch_length, trunk_top_y + branch_length)

    # Draw left branch
    draw_line(trunk_top, left_branch_top)

    # Draw right branch
    draw_line(trunk_top, right_branch_top)

# Define tree parameters
trunk_bottom = (0, 0)  # starting point at origin
trunk_top = (0, 50)    # height of the trunk
branch_length = 30     # length of each branch

# Draw the tree
draw_tree(trunk_bottom, trunk_top, branch_length)

acad.prompt("Drawing of a tree is completed.\n")
```

In this script, we define a simple tree with a trunk and two branches. The `draw_tree` function calculates the positions for the branches based on the given trunk height and branch length. The `draw_line` function uses `pyautocad` to add lines to the model space, effectively drawing the tree.

Before you run this script, ensure that AutoCAD is open and you have a drawing ready to be automated, as the `pyautocad` library connects to a running instance of AutoCAD. This script puts a basic tree shape directly into your AutoCAD workspace.

Note: Customize the coordinates and other parameters as per your requirement to create a more complex or larger structure.

code pyautocad draw tree

To draw a basic representation of a tree in AutoCAD using Python and the PyAutoCAD library, you'll need to use basic shapes like lines and circles to represent the trunk and the foliage, respectively. Below is an example script showing how to draw a simple tree using these shapes:

```python
from pyautocad import Autocad, APoint

# Initialize AutoCAD
acad = Autocad(create_if_not_exists=True)
print(acad.doc.Name)

# Function to draw a tree
def draw_tree(base_x, base_y, trunk_height=5, trunk_width=1, foliage_radius=3):
    # Define base point
    base_point = APoint(base_x, base_y)
    
    # Draw trunk (a simple rectangle)
    trunk_bottom_left = base_point
    trunk_bottom_right = APoint(base_x + trunk_width, base_y)
    trunk_top_left = APoint(base_x, base_y + trunk_height)
    trunk_top_right = APoint(base_x + trunk_width, base_y + trunk_height)
    
    # Using polyline to draw the trunk
    acad.model.AddPolyline((trunk_bottom_left, trunk_top_left, trunk_top_right, trunk_bottom_right, trunk_bottom_left))
    
    # Draw foliage - a simple circle on top of the trunk
    foliage_center = APoint(base_x + trunk_width / 2, base_y + trunk_height + foliage_radius)
    acad.model.AddCircle(foliage_center, foliage_radius)

# Example usage
draw_tree(0, 0)

print("Tree drawn in AutoCAD")
```

### Explanation:
1. **PyAutoCAD Initialization**: We start by initializing a connection to AutoCAD. The `create_if_not_exists=True` argument will create an AutoCAD application instance if it doesn't already exist.
   
2. **Function `draw_tree`**:
   - **Parameters**: The function accepts parameters to customize the position and size of the tree (base position, trunk height and width, foliage radius).
   - **Trunk**: Drawn as a rectangle using `AddPolyline` connecting four points (bottom left, top left, top right, bottom right).
   - **Foliage**: Positioned above the trunk and drawn as a circle with `AddCircle`.

3. **Foliage Circle**: Positioned directly above the trunk with a center at `(base_x + trunk_width / 2, base_y + trunk_height + foliage_radius)`.

### Notes:
- Make sure to have AutoCAD running on your system and that the PyAutoCAD library is properly installed.
- This script creates a simplistic representation of a tree. You can enhance it by adding more details such as branches using additional lines.
- PyAutoCAD operates by automating AutoCAD's COM interface, which can lead to significant resource use if multiple instances are accidentally opened. Always ensure to manage AutoCAD sessions properly.

code pyautocad draw tree

Drawing a tree using `pyautocad` can be a bit abstract, as `pyautocad` is primarily designed for automating tasks in AutoCAD, such as creating and manipulating basic geometric shapes like lines, circles, and arcs. To create a tree, you will have to break it down into simpler components or use a library or predefined block in AutoCAD. Here, I'll show you a basic example using lines and arcs to make a simplistic tree shape.

First, make sure you have `pyautocad` installed and have access to AutoCAD.

```bash
pip install pyautocad
```

Then, you can use the following Python script to draw a simplified tree:

```python
from pyautocad import Autocad, APoint

# Initialize AutoCAD
acad = Autocad(create_if_not_exists=True)
acad.prompt("Hello, AutoCAD from Python\n")

# Define a function to draw a simple tree
def draw_tree(base_point, trunk_height=100, trunk_width=10, canopy_radius=60):
    # Draw trunk as a rectangle (two lines)
    trunk_bottom_left = base_point
    trunk_top_left = APoint(base_point.x, base_point.y + trunk_height)
    trunk_bottom_right = APoint(base_point.x + trunk_width, base_point.y)
    trunk_top_right = APoint(base_point.x + trunk_width, base_point.y + trunk_height)
    
    acad.model.AddLine(trunk_bottom_left, trunk_top_left)
    acad.model.AddLine(trunk_bottom_right, trunk_top_right)
    
    acad.model.AddLine(trunk_bottom_left, trunk_bottom_right)
    acad.model.AddLine(trunk_top_left, trunk_top_right)
    
    # Draw canopy as a simple circle
    canopy_center = APoint(base_point.x + trunk_width / 2, base_point.y + trunk_height + canopy_radius)
    acad.model.AddCircle(canopy_center, canopy_radius)

# Starting point
base_point = APoint(0, 0)

# Draw the tree
draw_tree(base_point)

acad.prompt("Drawing completed!\n")
```

### Explanation:

1. **Initialize AutoCAD**: Create a new or connect to an existing AutoCAD instance.
2. **Draw the Trunk**: Create a rectangle using lines to represent the trunk.
3. **Draw the Canopy**: Represent the canopy with a circle above the trunk.

### Note:
- This example assumes a very basic representation of a tree (a vertical rectangle for the trunk and a circle for the canopy). You can make it more complex by adding arcs or more detailed shapes for the branches and leaves.
- Make sure AutoCAD is installed and running on your system.
- This code assumes AutoCAD units are in a linear format compatible with your dimensions. Adjust sizes according to your requirements.

If you're seeking to use more complex shapes, consider creating a block in AutoCAD or expanding upon the given primitives through loops and additional calculations for branches and leaves.

code pyautocad draw tree

Creating a tree using PyAutoCAD involves using AutoCAD commands to draw basic shapes like lines, circles, and arcs. However, it's important to note that drawing complex shapes like trees with detailed branches and leaves might not be feasible solely with basic AutoCAD commands. You can create a simple abstract representation of a tree using lines for branches and circles for leaves.

Before you start, make sure you have the `pyautocad` library installed and AutoCAD running on your system. You can install `pyautocad` using pip:

```bash
pip install pyautocad
```

Here's a basic example of how you can draw a simplified tree using PyAutoCAD:

```python
from pyautocad import Autocad, APoint

def draw_tree(autocad, base_point, trunk_height=10, branch_length=5, branch_angle=30, leaf_radius=1):
    """
    Draws a simple tree structure.
    
    Arguments:
    autocad -- An instance of AutoCAD.
    base_point -- The starting point (APoint) for the tree trunk.
    trunk_height -- The height of the tree trunk.
    branch_length -- Length of each branch.
    branch_angle -- Angle between the trunk and the branches.
    leaf_radius -- Radius of the circle representing a leaf.
    """
    
    # Draw trunk
    trunk_top = APoint(base_point.x, base_point.y + trunk_height)
    autocad.model.AddLine(base_point, trunk_top)
    
    # Draw branches
    branch_top_left = APoint(trunk_top.x - branch_length, trunk_top.y + branch_length)
    branch_top_right = APoint(trunk_top.x + branch_length, trunk_top.y + branch_length)
    
    autocad.model.AddLine(trunk_top, branch_top_left)
    autocad.model.AddLine(trunk_top, branch_top_right)
    
    # Draw leaves
    autocad.model.AddCircle(branch_top_left, leaf_radius)
    autocad.model.AddCircle(branch_top_right, leaf_radius)

if __name__ == "__main__":
    acad = Autocad(create_if_not_exists=True)
    start_point = APoint(0, 0)  # Base point for the tree
    draw_tree(acad, start_point)
```

### Explanation:
- **Trunk:** A line is drawn representing the trunk of the tree.
- **Branches:** Two lines are drawn at an angle from the top of the trunk to represent branches.
- **Leaves:** Circles are drawn at the ends of the branches to represent leaves.

### Customization:
You can customize the `trunk_height`, `branch_length`, and `leaf_radius` to achieve different tree sizes and shapes. Adding more branches or varying their lengths and angles can create more complex and varied tree shapes.

This script is a starting point, and you can enhance it by adding more details as required. Ensure that AutoCAD is open and running, as the script interacts directly with an active AutoCAD session.

code pyautocad draw tree

To draw a simple tree using PyAutoCAD, you'll need to interact with AutoCAD's COM interface to create lines and other shapes that represent a tree. PyAutoCAD is a Python library that allows you to interact with AutoCAD using Python scripts. First, make sure you have PyAutoCAD installed. If not, you can install it using pip:

```bash
pip install pyautocad
```

Here's a simple example to draw a basic representation of a tree using lines and circles (for the trunk and leaves) in AutoCAD:

```python
from pyautocad import Autocad, APoint

def draw_tree(base_point, trunk_height=200, trunk_width=20, canopy_radius=50):
    # Initialize AutoCAD
    acad = Autocad(create_if_not_exists=True)

    # Calculate points for the trunk
    p1 = base_point
    p2 = APoint(p1.x, p1.y + trunk_height)
    
    # Draw the trunk (rectangle)
    p3 = APoint(p1.x + trunk_width, p1.y)
    p4 = APoint(p3.x, p3.y + trunk_height)
    acad.model.AddLine(p1, p2)
    acad.model.AddLine(p1, p3)
    acad.model.AddLine(p2, p4)
    acad.model.AddLine(p3, p4)

    # Draw the canopies (circles)
    canopy_center1 = APoint(p2.x - trunk_width / 2, p2.y + canopy_radius)
    canopy_center2 = APoint(p2.x + trunk_width / 2, p2.y + canopy_radius)
    canopy_center3 = APoint(p2.x, p2.y + canopy_radius + trunk_height / 4)

    acad.model.AddCircle(canopy_center1, canopy_radius)
    acad.model.AddCircle(canopy_center2, canopy_radius)
    acad.model.AddCircle(canopy_center3, canopy_radius)

if __name__ == "__main__":
    base_point = APoint(0, 0)
    draw_tree(base_point)
```

### Explanation:
- **Trunk**: A simple rectangle represents the trunk.
- **Canopy**: Three circles above the trunk represent the tree's canopy.
- **APoint**: Defines points in AutoCAD space.
- **addLine**: Used to create lines between two points.
- **addCircle**: Used to create circles at specified centers and radii.

### Notes:
- This script creates a very basic tree. AutoCAD's drawing capabilities are extensive, so you can enhance this with more detailed and realistic designs.
- Ensure AutoCAD is running and accessible. PyAutoCAD will connect to the running instance or start a new one if specified.
- You may need to adjust the parameters like trunk width, height, and canopy radius for scale and fit in your particular drawing.

This example is just a starting point. Depending on your needs, you can expand it with more details and complexity.

code pyautocad draw tree

Creating a tree drawing with PyAutoCAD requires multiple steps to define the tree's structure through AutoCAD entities such as lines or polyline segments. Below is a basic example to illustrate how you might script a hierarchical, schematic tree using the `pyautocad` library. This doesn't produce a visually detailed tree but represents a conceptual tree structure.

First, ensure you have the `pyautocad` library installed and AutoCAD running on your system because the script interacts directly with AutoCAD.

Here's a basic script to draw a simple schematic tree:

```python
from pyautocad import Autocad, APoint

# Initialize AutoCAD
acad = Autocad()

def draw_tree(base_point, trunk_height, canopy_radius):
    # Draw the trunk
    top_of_trunk = APoint(base_point.x, base_point.y + trunk_height)
    acad.model.AddLine(base_point, top_of_trunk)
    
    # Draw a simple circular canopy using lines (or polyline for actual circle)
    # For simplicity, we'll draw a hexagonal canopy
    angle_step = 60  # degrees, for hexagon
    import math
    for i in range(6):
        angle_rad = math.radians(i * angle_step)
        next_angle_rad = math.radians((i + 1) * angle_step)
        
        start_point = APoint(
            top_of_trunk.x + canopy_radius * math.cos(angle_rad),
            top_of_trunk.y + canopy_radius * math.sin(angle_rad)
        )
        
        end_point = APoint(
            top_of_trunk.x + canopy_radius * math.cos(next_angle_rad),
            top_of_trunk.y + canopy_radius * math.sin(next_angle_rad)
        )
        
        acad.model.AddLine(start_point, end_point)

# Define starting point and dimensions
base_point = APoint(0, 0)
trunk_height = 5    # Tree trunk height
canopy_radius = 3   # Radius of the tree's canopy

# Draw a tree
draw_tree(base_point, trunk_height, canopy_radius)
```

### Notes:
1. **Dependencies**: This script requires the `pyautocad` library, which can be installed via pip (`pip install pyautocad`). Additionally, AutoCAD and its COM interface must be installed and fully configured on your machine.

2. **Approach Explanation**: The above script starts by drawing a vertical line representing the tree trunk. It then draws a simple hexagonal canopy on top of the trunk to simulate the tree's leaves or canopy. If you need more complex shapes, consider using AutoCAD's circles or arcs for better visual effects.

3. **Extension Ideas**: 
   - You could refine this script by using more complex shapes for the canopy.
   - Add branching by introducing lines or arcs that represent tree branches stemming from the trunk.
   - Experiment with different geometric patterns to create more elaborate tree forms.

This example is simplified and may need adaptation for more comprehensive use cases or more sophisticated tree modeling using AutoCAD facilities directly for circles and more complex polygons.

code pyautocad draw tree

Creating a tree structure using the `pyautocad` library involves using lines, arcs, or other shapes to represent the trunk, branches, and leaves of the tree. Below, I provide a simple example of how you might use PyAutoCAD to draw a basic tree schematic.

First, ensure that you have the `pyautocad` library installed. You can install it using pip if you haven't already:

```bash
pip install pyautocad
```

Next, create a Python script that uses the AutoCAD API to draw a tree:

```python
from pyautocad import Autocad, APoint

def draw_tree():
    acad = Autocad(create_if_not_exists=True)
    acad.prompt("Creating a tree...\n")
    
    # Root point for the tree
    base_point = APoint(0, 0)
    
    # Draw the trunk
    trunk_height = 50  # Adjust as needed
    trunk_width = 5  # Adjust as needed
    trunk_start = base_point
    trunk_end = APoint(0, trunk_height)
    acad.model.AddLine(trunk_start, trunk_end)
    # Optional: Draw trunk width
    acad.model.AddLine(APoint(-trunk_width / 2, trunk_height), APoint(trunk_width / 2, trunk_height))
    acad.model.AddLine(APoint(-trunk_width / 2, 0), APoint(-trunk_width / 2, trunk_height))
    acad.model.AddLine(APoint(trunk_width / 2, 0), APoint(trunk_width / 2, trunk_height))

    # Draw branches
    branch_length = 30  # Adjust as needed
    angle_offset = 15  # Angle in degrees
    for angle in range(-60, 90, 30):
        x_offset = branch_length * math.cos(math.radians(angle))
        y_offset = branch_length * math.sin(math.radians(angle))
        branch_start = APoint(0, trunk_height)
        branch_end = APoint(x_offset, trunk_height + y_offset)
        acad.model.AddLine(branch_start, branch_end)

    # Draw leaves
    leaf_radius = 10
    leaf_positions = [
        (branch_end.x, branch_end.y) for branch_end in [APoint(branch_length, trunk_height + 10), APoint(-branch_length, trunk_height + 10)]
    ]
    for pos in leaf_positions:
        center = APoint(*pos)
        acad.model.AddCircle(center, leaf_radius)
    
    print("Tree drawing completed!")

if __name__ == "__main__":
    draw_tree()
```

### Description:
- **Trunk**: The trunk is a simple vertical line with optional width lines for visual thickness.
- **Branches**: Branches are lines drawn at various angles from the top of the trunk.
- **Leaves**: Simple circles are drawn at the ends of certain branches to represent leaves.

### Important Notes:
- This code assumes that AutoCAD is installed and accessible on your system and that you have initialized a drawing session.
- The drawing is extremely basic. Realistic trees would require complex logic to simulate branching and foliage patterns.
- Adjust the parameters to fit your design needs, such as adjusting the trunk width, tree height, branch angles, and leaf placements.

Run this code in an environment where AutoCAD is properly configured to see the results directly in AutoCAD. The above example provides a foundational basis for experimenting with `pyautocad` to draw more complex shapes and figures.

code pyautocad draw tree

Drawing a tree using the PyAutoCAD library involves creating a structure of lines and shapes that resemble a tree. PyAutoCAD allows you to automate tasks in AutoCAD using Python.

Below is an example code snippet that uses PyAutoCAD to draw a simple tree. This tree will consist of a trunk (a rectangle) and a canopy (a circle or polygon to represent the leaves).

Before running the script, ensure that you have AutoCAD installed and PyAutoCAD set up in your Python environment. You can install PyAutoCAD using pip if you haven't already:

```bash
pip install pyautocad
```

Here is a simple example to draw a tree:

```python
from pyautocad import Autocad, APoint

# Initialize AutoCAD
acad = Autocad(create_if_not_exists=True)
acad.prompt("Hello! Creating a tree...")

# Define trunk dimensions
trunk_base = APoint(0, 0)
trunk_width = 2
trunk_height = 5

# Draw trunk
p1 = trunk_base
p2 = APoint(trunk_base.x, trunk_base.y + trunk_height)
p3 = APoint(trunk_base.x + trunk_width, trunk_base.y + trunk_height)
p4 = APoint(trunk_base.x + trunk_width, trunk_base.y)

for start, end in [(p1, p2), (p2, p3), (p3, p4), (p4, p1)]:
    acad.model.AddLine(start, end)

# Define canopy
canopy_center = APoint(trunk_base.x + trunk_width / 2, trunk_base.y + trunk_height + 3)
canopy_radius = 4

# Option 1: Draw a circular canopy
acad.model.AddCircle(canopy_center, canopy_radius)

# Option 2: Draw a polygon canopy (e.g., triangle)
# Note: Uncomment this section if you prefer a triangular canopy
# p5 = APoint(canopy_center.x - canopy_radius, canopy_center.y)
# p6 = APoint(canopy_center.x + canopy_radius, canopy_center.y)
# p7 = APoint(canopy_center.x, canopy_center.y + canopy_radius)
# for start, end in [(p5, p6), (p6, p7), (p7, p5)]:
#     acad.model.AddLine(start, end)

print("Tree has been drawn!")
```

### Key Points:
- **Trunk**: Represented by a rectangle created using four lines.
