# SVG to Multi-Color 3D Model Converter
# Automatically detects all colors in SVG and creates one part per color
# Note: The DYLD_LIBRARY_PATH is needed for Cairo to work on macOS

# Basic usage - specify width, logo scales proportionally
export DYLD_LIBRARY_PATH="/opt/homebrew/lib:$DYLD_LIBRARY_PATH" && source .venv/bin/activate && python svg_logo_to_stl.py "Color logo - no background.svg" logo_output --width-mm 254 --base-thickness 1.5 --feature-height 2.5

# Plate dimensions - logo scales and centers on specified plate size with margin
python svg_logo_to_stl.py underground-magnetics-combined.svg um_logo --plate-width 256 --plate-height 256 --margin 10 --base-thickness 1.5 --feature-height 2.5

# Or if you've already activated the venv and set the library path:
python svg_logo_to_stl.py "Color logo - no background.svg" logo_output --width-mm 254 --base-thickness 1.5 --feature-height 2.5

# Works with ANY SVG file! The script will:
# 1. Automatically detect all unique colors
# 2. Create one part per color
# 3. Generate assembly with separate selectable parts

# Output files:
# - logo_output_base.stl - Black base plate
# - logo_output_{color}.stl - One STL per detected color
# - logo_output_assembled.stl - All parts combined (single mesh)
# - logo_output_assembled.3mf - All parts as single mesh (for paint tool)
# - logo_output_parts.3mf - Separate selectable parts (BEST for multi-color!)

# Import logo_output_parts.3mf into BambuStudio
# Each detected color becomes a separate selectable part
# Assign different filaments to each part for multi-color printing

# Example for this logo:
#   1. base - black base plate
#   2. white - "SPARKSOFT DESIGN" text
#   3. green - microchip icon + "EMBEDDED SOLUTIONS" text

# Total model height: base_thickness + feature_height (default: 0.8mm + 1.8mm = 2.6mm)

# IMPORTANT: Scale must be 254mm or larger for 0.4mm nozzle
# Smaller sizes cause features to be too small for proper toolpath generation

# Parameters:
#   --width-mm: Logo width in mm (if plate dimensions not specified)
#   --plate-width: Plate width in mm (logo will be scaled and centered)
#   --plate-height: Plate height in mm (logo will be scaled and centered)
#   --margin: Margin around logo when using plate dimensions (default: 0)
#   --base-thickness: Base plate thickness in mm (default: 0.8)
#   --feature-height: Raised feature height in mm (default: 1.8)
