产品工程蓝图：基于参考图转 orthographic

为 Nano Banana Pro 或 GPT Image 设计的 prompt，根据参考图生成详细蓝图：分析上传的参考图以理解物体的机械结构与几何。生成该具体产品的综合工业级蓝图。以专业正射投影方式呈现，包含清晰的平面、立面与剖视图，详细内部与外部构造。将装配分解为各主要组件，并使用标准化无衬线工程字体为每个部件添加清晰可读的技术文本标签（编号）。以经典蓝图美学呈现，配白色矢量线条与深蓝网格背景，确保高对比度与专业精度，适合制造文档。

Analyze the uploaded reference image to understand the mechanical structure and geometry of the object. Generate a comprehensive, industrial-level blueprint of this specific product. Present the design as a professional orthographic projection, featuring clear plan, elevation, and section views to detail the internal and external construction. Deconstruct the assembly into its primary components and apply legible, technical text labels (denominations) for each part using a standardized sans-serif engineering font. Render the visual in a classic blueprint aesthetic with precise white vector-style lines on a deep blue grid background, ensuring high contrast and professional accuracy suitable for manufacturing documentation.
