CATIA → STL · Online Conversion Guide
Key values of CATIA → STL conversion include: 从 CATIA 模型快速得到打印/制造可用三角网格 去除语义仅保留几何外壳用于切片 统一输出便于下游加工
CATIA: CATIA is Dassault Systèmes’ high‑end CAD/PLM platform used in aerospace and automotive. Native formats are CATPart/CATProduct, excellent for complex surfaces and large assemblies.
STL as the target format: STL is commonly used for 3D printing/rapid prototyping, keeping triangle shells only (no materials/hierarchy).
Practical tips: 原生导入支持：直接上传 CATPart/CATProduct; 导出后检查非流形/自交并做修复；合理设置离散公差.
Typical scenarios: Complex surfacing, final assembly integration, digital mockups.

- 统一输出便于下游加工
Quick steps
- Upload CATIA on the homepage
- Choose STL as the output and convert
- For very large models, run 3D Tiles tiling
- Open the 3D viewer for interactive preview/sharing

FAQ
Q: What information may be lost from CATIA to STL?
Parametric features/constraints/history become polygon meshes; verify materials and textures.
Q: How to reduce size for CATIA → STL?
Remove hidden parts, lower tessellation where acceptable, compress textures, enable Draco, merge materials.
Q: Batch or very large models supported?
Use 3D Tiles tiling for massive assemblies; consider splitting by hierarchy/area.
Q: Can I further edit after converting?
After converting to STL, geometry is mesh-based; you can clean meshes and tweak materials, but parametrics are not preserved.
