+> *CadQuery Viewer case: one prompt asks the Agent to design a 3D-printable MiniMax octopus figure, and the model takes shape live beside the conversation.* The Agent looks up the official mascot for reference, writes a parametric CadQuery script, runs and fixes it, and pushes each build to the Viewer on the right. You can orbit, switch views, and section the model at any point, then get print settings and a table of tunable parameters—pick what to change and let the Agent rebuild.

 **MiniApp's product stance: keep people involved in collaboration and decisions (Human-in-the-Loop).**
 
 We respect every industry, every profession, and the expertise people build over time. AI should be your smartest executor—amplifying your capabilities rather than pretending to have professional judgment on your behalf. MiniApps reconnect the part of the process that is too often split apart: turning work from something that can be refined into something that can be delivered.

+> *CadQuery Viewer 案例：一句话让 Agent 设计一个可 3D 打印的 MiniMax 小章鱼玩偶，模型在对话旁实时成形。* Agent 先查官方形象作参考，再编写 CadQuery 参数化脚本、自己运行并修正问题，每次构建都推送到右侧的 Viewer。你可以随时旋转、切换视角、剖切检查模型，最后拿到打印建议和一张可调参数表——决定改哪一项，再让 Agent 重新出图。
