## What is 3D Mesh Doctor?

3D Mesh Doctor is a powerful yet easy-to-use 3D mesh repair and optimization tool designed for iOS and iPadOS. Whether you're a 3D printing enthusiast, AR/VR developer, 3D scanning professional, or industrial modeler, this app provides everything you need to fix and optimize your 3D models on the go.

Key Features:

• Mesh Diagnosis: Automatically analyze your 3D models and generate detailed health reports. Detect issues including non-manifold edges, holes, degenerate triangles, duplicate vertices, and self-intersections.

• Auto Repair: One-click automatic repair to fix common mesh problems. Remove duplicate vertices, fix non-manifold geometry, fill holes, remove degenerate triangles, and recalculate normals.

• Smart Decimation: Reduce mesh face count intelligently while preserving model quality. Choose from Extreme (10%), Balanced (30%), or Quality (60%) modes to optimize models for different use cases.

• Format Conversion: Seamlessly convert between STL, OBJ, and USDZ formats. Export to USDZ for ARKit and RealityKit applications.

• Real-time Preview: View your 3D models with rotation, zoom, and pan capabilities using RealityKit-powered rendering.

Supported File Formats:
STL, OBJ, USDZ

Perfect for:
- 3D printing preparation
- AR/VR content optimization
- 3D scan cleanup
- Industrial modeling
- Mobile 3D workflows

Free version includes diagnosis, repair, decimation, and conversion. Upgrade to Pro to export your processed models.

## Version history (last 2 releases)

### 1.1 — 2026-06-12

#### New Features
- **Island Removal**: Added a new mesh repair step that automatically detects and removes small disconnected components (islands). This is ideal for cleaning up noise and floating geometry in 3D scans.
- **Improved UI**: Integrated a new toggle in Settings -> Performance to enable or disable Island Removal.

#### Bug Fixes & Improvements
- **Mesh Engine Stability**: Enhanced the core repair algorithm to better handle non-manifold edges during the island removal process.
- **Wireframe Fix**: Resolved an issue where the mesh would not display correctly in wireframe mode, ensuring clear visualization of the model's topology.

### 1.0 — 2026-03-31

No release notes.
