Technical Illustration Skill

This skill provides methods for generating technical illustrations, specifically exploded-view diagrams, using Python's Pillow library.

Components of an Exploded View

An exploded-view diagram separates parts of a whole along a common axis (usually vertical or at an angle) to show internal assembly.

Layering Strategy

Casing (Top): Usually Corporate Dark or Neutral.
Thermal Unit: Below casing, often using secondary accents.
PCB (Printed Circuit Board): Below thermal unit, often using tertiary accents.
Battery: Below PCB.
Interface (Bottom): Connector highlights, primary accents.

Annotation System

Leader Lines: Thin lines connecting components to labels. Use Muted Mid Gray.
Title Block: Clear, bold heading in the top-left or specified location.

Python (Pillow) Implementation Pattern

1. Canvas Setup

from PIL import Image, ImageDraw, ImageFont

# Initialize canvas with background identity color
canvas = Image.new('RGB', (2000, 2000), '#FAF9F5')
draw = ImageDraw.Draw(canvas)

2. Drawing Components

Represent hardware parts as stylized geometric shapes (rectangles with rounded corners or trapezoids for perspective).

# Example: Drawing a layer (isometric-style)
def draw_layer(draw, top_y, color, width=600, height=400, offset=100):
    # Stylized trapezoid to simulate perspective
    points = [
        (1000 - width//2, top_y),
        (1000 + width//2, top_y),
        (1000 + width//2 + offset, top_y + height),
        (1000 - width//2 - offset, top_y + height)
    ]
    draw.polygon(points, fill=color, outline='#B0AEA5')

3. Annotations

# Leader line logic
draw.line([(x1, y1), (x2, y2)], fill='#B0AEA5', width=2)
# Label logic (use Poppins if available, else standard)
draw.text((x2 + 10, y2 - 10), "LAYER NAME", fill='#141413')
