HELPER FUNCTIONS

============================================

Check if OpenSCAD is installed

check_openscad() { if ! command -v $OPENSCAD_CMD &> /dev/null; then echo -e “${RED}Error: OpenSCAD not found. Install it first.${NC}” echo “Ubuntu/Debian: sudo apt-get install openscad” echo “macOS: brew install openscad” exit 1 fi }

Create output directory

setup_output() { mkdir -p “$OUTPUT_DIR” echo -e “${YELLOW}Output directory: $OUTPUT_DIR${NC}” }

Find all SCAD files

find_scad_files() { echo “Searching for SCAD files…” while IFS= read -r file; do SCAD_FILES+=(“$file”) done < <(find . -name “*.scad” -type f | sort)

if [ ${#SCAD_FILES[@]} -eq 0 ]; then
    echo -e "${RED}No SCAD files found!${NC}"
    exit 1
fi

echo -e "${GREEN}Found ${#SCAD_FILES[@]} SCAD files${NC}"

}

Compile a single SCAD file

compile_scad() { local scad_file=“$1” local output_file=“${OUTPUT_DIR}/$(basename “$scad_file” .scad).stl“

echo -n "Building: $scad_file ... "

if $OPENSCAD_CMD -o "$output_file" "$scad_file" 2>/dev/null; then
    echo -e "${GREEN}✓ Success${NC}"
    SUCCESS_COUNT=$((SUCCESS_COUNT + 1))
    return 0
else
    echo -e "${RED}✗ Failed${NC}"
    FAILED_COUNT=$((FAILED_COUNT + 1))
    return 1
