## What is 3D Model Viewer & Converter?

3D Model Viewer & Converter helps you inspect parts, slice cross sections, generate orthographic views, and export clean results across macOS, iPad, and iPhone. It works offline, keeps your files local, and is built for engineers, makers, designers, and 3D file users who need a lightweight way to review models before converting, exporting, or sharing them.

Key Features
• Import a wide range of 3D and point cloud formats, including 3MF, STL, FBX, OBJ, GLB, USDZ, MPD/LDR, DAE, TDS, AMF, LAS, PLY, PCD, XYZ, VOX, VTK, VTP, and DXF
• Review a model information summary after loading, with quick access to format, file size, object/mesh/point counts, triangles, dimensions, materials, and textures
• Inspect internal geometry with XY, XZ, and YZ cross sections, including automatic scan slicing and manual control of slice positions
• Use exploded view to separate model components, inspect multipart assemblies more clearly, focus or pin individual parts, and export selected exploded parts to clean 3D files
• Generate orthographic projection outputs — including front, top, and right views — in SVG format
• Export clean 3D results to STL, OBJ, GLB, USDZ, and GLTF
• Batch convert multiple source files — even across different model formats — into one target format in a single workflow
• Capture model screenshots for export or sharing
• Manage recent files with individual deletion and one-tap clearing to keep the entry point tidy
• Basic editing tools: move, rotate, scale, delete, and undo changes to model objects

### 1/5 — This sucks

*2026-08-02*

You have to pay to do anything. At this point, just make the app paid

**Developer response:** Viewing all twenty-plus model formats is free; only advanced features (such as exploded views and cross-sections) and model format conversion/export come with a fee. You can choose to permanently unlock specific features as needed or subscribe for access to the full suite of functions.

### 2/5 — Size Limits

*2026-07-03*

I paid my $3.99 only to find out the file I wanted to work with was too big. Very disappointing. It’s basically worthless for anything remotely complicated.

**Developer response:** We’re very sorry for the inconvenience and disappointment caused by the file size limitation. We completely understand your frustration, especially after purchasing the app and finding that your file could not be opened.

Could you please let us know the size of the file you were trying to load (how many MB, or GB)? We’d like to better understand the situation and see if we can help.

If the app doesn’t meet your needs, you can also request a refund directly through the App Store. Alternatively, please feel free to contact us at [danjian42@gmail.com](mailto:danjian42@gmail.com), and we will do our best to assist you.

Thank you for your feedback — it helps us continue improving the app.

### 2/5 — Can’t open any STL Files!

*2026-03-18*

This app shows failure to load when trying to read any STL files. It won’t load STL files that other apps will. It does work with other supported file types.

**Developer response:** Please send any files that caused the failure to me: danjian42@gmail.com, seriously. Thank you for you feedback.

### 5/5 — My favorite 3d print slicer app

*2025-12-29*

It works well

## Version history (last 5 releases)

### 1.1.4 — 2026-08-11

- Added automatic multi-model layout and size fitting. Models of different sizes are normalized to a consistent visual scale and arranged in a grid, which expands automatically beyond 9 models.
- Automatic layout includes a global toggle and remembers your setting. When disabled, models continue to be appended on the right; the helper grid and camera framing also adapt to the current layout.
- Fixed an issue where deleted recent files could reappear after restarting the app. Deleting a recent file now also removes its saved history record and the corresponding file from the import folder.
- Improved two-finger pinch and scroll gestures on trackpads, mouse-wheel zoom, and touch zoom for smoother, more precise size control.
- Expanded onboarding with guidance for the view orientation helper in the bottom-right corner, plus clearer explanations of how Exploded View, Orthographic Projection, and Cross Section work in multi-model scenes.
- Added Spanish, Turkish, and Russian interface support.

### 1.1.3 — 2026-06-15

- Added support for importing LAS point cloud files (.las extension) for viewing lidar, surveying, and industrial point cloud data.
- Added a model information summary panel after loading, with quick access to format, file size, object/mesh/point counts, triangles, dimensions, materials, and textures.
- Recent files now support deleting individual records and clearing the full list, with a more compact layout.
- Fixed an issue where STLB binary data could be empty when exporting exploded parts to ZIP.
- Fixed an issue where large SVG files, including SVG files exported by the app itself, could hang or appear invisible when imported again.

### 1.1.2 — 2026-05-22

- Added Explore & Export for exploded parts: select individual parts, highlight them in the scene, quickly focus the camera, and pin a single part for isolated inspection.
- Exploded parts export: select multiple parts and export them continuously in batch, organize output folders by model name, and see progress plus completion feedback.
- Improved loading stability for certain STL files.

### 1.1.1 — 2026-04-27

- Updated the App Store presentation to make supported 3D formats, inspection tools, and local workflow benefits clearer.

### 1.1.0 — 2026-04-23

- Clarified the inspection, section, projection, and conversion workflow to make the app's core tools easier to understand and use.
- Fixed save and share issues affecting PNG exports and Projection View SVG exports.
