PCB元件3D STEP模型查看器
PCB上的逼真3D元件
MakerSuite 3D为PCB元件加载真实的STEP 3D模型，用逼真的形状替代简单的方框，与板上的实际零件一致。
STEP模型加载方式
加载PCB文件时，MakerSuite 3D将每个元件的封装与托管在Cloudflare R2 CDN上的116+个STEP模型库进行匹配。距离摄像机最近的元件优先加载。
元件库覆盖范围
- 电阻 — 0402、0603、0805、1206、1210、2512封装
- 电容 — MLCC、电解、钽常用尺寸
- IC — QFN、QFP、LQFP、TSSOP、SOT-23、SOT-223、SOIC封装
- 连接器 — USB-C、USB Micro-B、排针、JST
- 被动元件 — 电感、二极管、LED、晶振、开关
- 模块 — ESP32-WROOM、热门开发板组件
自定义STEP模型上传
缺少元件？在详细面板中直接上传STEP (.step/.stp)或STL文件。自定义模型保存在浏览器的IndexedDB中，跨会话持久保存。

Frequently Asked Questions
How many 3D STEP models are available?
Over 116 component models are available via Cloudflare R2 CDN, covering resistors, capacitors, ICs, connectors, modules, and more.
Can I upload custom STEP models?
Yes. You can upload your own .step or .stp files and they'll be cached in IndexedDB for instant loading on future visits.
How are components matched to 3D models?
An IPC-7351 footprint matcher combined with manufacturer MPN lookup automatically finds the correct 3D model with up to 97.8% match rate.
What happens if a 3D model isn't available?
A proportionally-sized fallback box is rendered based on the component's pad dimensions, so you still see accurate board layout.
