在产品开发、学术论文写作和专利申请中,我们需要大量的“技术说明图”。这些图不需要华丽的渲染,只需要清晰的结构。以前,这需要熟练掌握 CAD 或 SolidWorks 的工程师画很久。现在,通过**“精密科学蓝图转换器 (VIA-Spec V2.0)”**,我们可以让 Midjourney 等 AI 模型瞬间生成极具专业感的工程图纸。

核心特征说明
🛠️ 工程转译:剥离光影材质,只保留几何结构。AI 瞬间化身老工程师,画出最严谨的线条。 🟦 风格百变:支持“经典蓝晒图 (Cyanotype)”的复古美感,也支持“黑白专利图 (Patent)”的严谨冷峻。 💣 视图切换:想看内部?开“剖面模式”。想看装配?开“爆炸视图”。 📏 精准锚定:配合图生图(Img2Img),AI 能提取照片的轮廓,自动转化为矢量风格的线稿。
关键技术拆解
🔑 视觉逻辑:De-materialization (去材质化) AI 生图通常倾向于“加法”(加光影、加纹理)。这套 Prompt 做的是“减法”。我们要求 Linework should be clean, sharp, and schematic。这迫使模型剥离物体表面的颜色和反光,回归到物体的本质——几何形状和拓扑结构。
🔑 交互变量:Analysis Mode (分析模式) 为了适应不同的工程需求,我们定义了三种核心视图:
-
Exploded View (爆炸图):将零件沿轴线拆解,展示装配关系。适合机械结构展示。
-
Cutaway View (剖面图):切开外壳,展示内部核心组件。适合展示引擎、电机等复杂设备。
-
Orthographic Projection (正投影):标准的顶视、侧视、正视三视图。适合作为建模参考图。
🔑 扩展思路:Da Vinci Manuscript Mode (达芬奇手稿模式) 这套逻辑不仅可以用于现代工业,还可以用于艺术创作。 将 technical_style 改为 Vintage Da Vinci Sketch, sepia ink on old parchment(复古达芬奇素描,旧羊皮纸上的深褐色墨水),你就能得到一张仿佛来自文艺复兴时期的机械手稿,非常适合作为装饰画或游戏道具设计。

实际使用场景
这套系统是“硬核内容”的生产力工具:
场景一:专利申请配图。生成黑白线条图,清晰展示发明的外观设计,符合专利局的格式要求。 场景二:工业设计提案。用蓝晒图风格展示产品的结构美学,提升提案的格调。 场景三:学术论文插图。为你的论文生成原理示意图,替代简陋的手绘图。 场景四:复古装饰艺术。生成飞机、汽车或咖啡机的复古蓝图,打印装裱作为家居装饰。
通过这套 Prompt,AI 不再是一个只会画画的画家,而变成了一个懂结构的工程师。以下是完整的 JSON 协议,复制它,定义你的对象和视图模式,开始绘制你的蓝图吧。
