Technical Drone Engineering Blueprint

A detailed technical engineering sheet for a quadcopter drone, showing orthographic views, part drawings, assembly diagrams, exploded views, cross-sections, and a BOM table with full dimension annotations. Small concept sketches appear in the corners, giving the image the feel of a complete manufacturable product blueprint.

{argument name="产品" default="四轴无人机"} 带尺寸工程图，包括不限于下面这些内容，记得角落做一些产品概念图  三视图：主视图、俯视图、左视图，用二维表达三维结构 零件图：每个零件单独画，带尺寸、孔位、材料、公差 装配图：说明各零件怎么装在一起 爆炸图 / 爆炸装配图：把零件拆开排布，方便看结构关系 剖视图：把内部结构切开表达 BOM 表：物料清单，写明零件名称、数量、规格 尺寸标注图：把可制造、可复刻需要的关键尺寸写全
