Display an interactive 3D model in PowerPoint, Google Slides, or Keynote. Via OmniView 3D link, native 3D object, or GLB file: complete 2026 guide.
Presenting a product, mechanical part, or building in a client meeting lands much harder with an interactive 3D model than a static render. Here are the concrete methods to display a 3D model in PowerPoint, Google Slides, or Keynote, and their limits.
The most reliable method for all platforms: upload your model to OmniView 3D, get a viewer link, and insert it in your slide as a hyperlink or button. During the presentation, click the link, the 3D viewer opens in the browser. Works on any device, any format (STEP, GLB, FBX, OBJ). Zero dependency on the presentation software, and the same link later lets you embed the viewer on your website.
PowerPoint 365 on Windows supports inserting native 3D files. Go to Insert → 3D Models → from a file. The model rotates in real-time in the slide. Note one recent change: Microsoft turned off FBX file insertion in Office with the January 2024 security update. The formats to use today are GLB (Office's recommended 3D format), glTF, OBJ, STL, PLY, and 3MF. Key limitations: works only on PowerPoint Windows (not Mac, not web, not Google Slides), the model is invisible to viewers on other versions, and STEP files are not supported.
| Method | Interactive | All platforms | Supports STEP | Visible to every viewer |
|---|---|---|---|---|
| OmniView 3D link | Yes | Yes (browser) | Yes (STEP read natively) | Yes, via the link |
| Native PowerPoint 3D object | Yes | No (Windows only) | No (GLB/OBJ/STL…) | No (depends on version) |
| Rotation video / GIF | No | Yes | Via video export | Yes |
GLB is the pivot format in this chain: binary, compact, and now the recommended 3D format for Office, it builds on the Khronos Group glTF specification, standardized as ISO/IEC 12113:2022. To start from a STEP, follow our convert STEP to GLB guide.
Google Slides does not support native 3D objects. The only reliable method: insert the OmniView 3D link as a hyperlink on a button or preview image. During the presentation, click the button, the 3D viewer opens in the browser. You can also insert a rotation video via Insert → Video → YouTube or Google Drive.
No. PowerPoint's native 3D object supports GLB, glTF, OBJ, STL, PLY, and 3MF (FBX insertion has been turned off since January 2024). To display a STEP in a presentation, export it as GLB from your CAD tool, or use OmniView 3D: upload the STEP, share the viewer link, insert the link in PowerPoint.
Keynote on Mac and iPad supports USDZ and some native 3D formats. Export from Blender as USDZ or use Apple's Reality Converter tool. Alternatively, an OmniView 3D link works from any Mac in Safari during a presentation, with no installation.
No, not since the January 2024 security update: Microsoft turned off FBX file insertion in Office. Convert your FBX to GLB, now Office's recommended 3D format, then insert it via Insert → 3D Models.
