机构怎么动、零件里面发生了什么、为什么这样设计——用平台已有的模型和算出来的运动，自动出讲解视频。不用装软件，浏览器里用。How a mechanism moves, what happens inside, why it is designed that way: explanation videos made automatically from the platform's models and computed motion. Nothing to install; it runs in the browser.
全部由平台按场景文件自动渲染，没有手工剪辑。All rendered automatically from scene files; no manual editing.
整机转起来 → 去外盖 → 跟着机针钻到针板下 → 旋梭钩住线环、套过梭壳 → 在布中间扣成线结 → 回到整机。连看实物都难懂的一下，讲清楚了。The whole machine runs → covers off → follow the needle below the plate → the hook catches the loop and carries it round the bobbin case → the threads lock inside the cloth → back to the machine. The step that is hard to see even on a real machine, made clear.
剖开机壳，看上轴、针杆、挑线杆、下轴、旋梭怎样配合；慢放约 2000 倍，右侧读数和针尖高度曲线跟着机构实时走。The casing cut open: main shaft, needle bar, take-up, lower shaft and hook working together, about 2000× slower, with live readouts and the needle-height curve.
逆运动学算出每个关节角；透视看到关节里的电机和减速器，关节角面板逐帧跟着走。Every joint angle computed by inverse kinematics; X-ray shows the motors and reducers inside the joints, with the joint panel following frame by frame.
同一台平缝机，换成写实光照、景深和配音，适合产品展示和宣传。The same machine with realistic lighting, depth of field and narration, for product showcases and promotion.
机械臂按逆运动学、整机按虚拟样机的机构计算，读数可信，能写进报告和课件；不是动画师手调的。Arms follow inverse kinematics and machines their own mechanism model, so the numbers can go into reports and courses. Nothing is hand-keyed.
剖开、透视、慢放、特写、读数面板和曲线，按讲解需要组合；中英标注，可加配音。Cutaways, X-ray, slow motion, close-ups, readout panels and curves, combined as the explanation needs; bilingual labels and optional narration.
说要什么，AI 写场景；先看关键画面（1–2 分钟），再出小样（约 10 分钟）和高清（约 30 分钟）。逐条提意见，AI 改。Say what you want and the AI writes the scene; key frames in 1–2 minutes, a draft in about 10 minutes and HD in about 30. Give feedback and the AI revises.
SolidWorks 负责设计和算，问渠负责讲出来、教出去。SolidWorks designs and computes; WenQuest explains and teaches.
我们不和 SolidWorks、ADAMS、RoboDK 等比求解和建模。它们出的是动画本身，讲解字幕、中英标注、读数、配音还要另外做，一段一段手调；我们补的是这一段：不会这些软件的老师、学生、销售也能一句话出片，可以批量出，直接插进课件和白板课。企业的装配可以导出 STEP 交给我们接入。We do not compete with SolidWorks, ADAMS or RoboDK on solving or modelling. They produce the animation itself; captions, bilingual labels, readouts and narration still have to be added by hand, clip by clip. We fill that gap: teachers, students and sales staff who do not use those tools get a video from one sentence, in batches, ready for slides and whiteboard lectures. Company assemblies can be brought in by sending us a STEP export.
