How to Embed a 3D Model in PowerPoint, Google Slides, or Keynote

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.

Method 1 — OmniView 3D Link (Recommended for All Platforms)

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.

Method 2 — Native 3D Object in PowerPoint (Windows Only)

PowerPoint 365 on Windows supports inserting native 3D files (GLB, GLTF, OBJ, FBX, STL, PLY, 3MF). Go to Insert → 3D Models → from a file. The model rotates in real-time in the slide. 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.

1. 1Export your model as GLB from your CAD tool or Blender
2. 2In PowerPoint Windows: Insert → 3D Models → This Device
3. 3Select the GLB file
4. 4In presentation mode: rotate with the mouse in real time

How do I insert a 3D model into Google Slides?

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.

Does PowerPoint support STEP files?

No. PowerPoint's native 3D supports only GLB, GLTF, OBJ, FBX, STL, PLY, and 3MF. 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).

How do I rotate a 3D model in Keynote on Mac?

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.

What is the best way to show a 3D model in a sales presentation?

The most robust approach: use OmniView 3D. Upload your STEP or GLB model, embed the link in your deck as a full-screen button. During the pitch, click it — the viewer opens at full browser width. No plugin, no PowerPoint version dependency, works on the client's screen sharing too. Sales teams at B2B manufacturers use this to show complex products to procurement teams in real time.
