Full CAD on Duo
Duo is about the size of an iPad mini, with Apple Pencil support. It's big enough to model in real detail and compact enough to carry everywhere. That makes it the most portable full CAD setup Shapr3D has ever run on. Here's what you'll get:
- Sketch with Apple Pencil and model in detail
- Same Parasolid engine as iPad, Mac, and Windows
- Materials, custom materials, and decals for lifelike presentations
- Projects sync across all your devices
- On-device processing, so everything runs locally on Duo.

Design within reach, on every screen
Our goal is simple: make 3D design easy to reach, for everyone, wherever they are. That doesn't mean squeezing the same app onto every screen. We asked what you actually need with each device in hand. On Duo, that's a full-featured 3D modeling software you can take anywhere. On every other iPhone, it's a fast, focused viewer, so anyone on the team can open a model without learning CAD. Viewer or full editor, your designs are always a tap away.
This is a first version, so tell us what's missing. Your feedback goes straight to the team building them.
A viewer for every other iPhone
Apple Pencil support is exclusive to Duo, so every other iPhone will get the Shapr3D viewer. Here's what it will do:
- Import anything: STEP, SLDPRT, X_T, STL, DWG, and more, even without Shapr3D on another device
- Display modes: Visualized, wireframe, and X-ray views
- AR at full scale: Check size, fit, and proportions in the real world
- High-res screenshots: Crisp images for decks, posts, and client updates
- Generative Render: Describe a scene and get a photorealistic render in seconds
- Export anywhere: STEP, IGES, X_T, STL, 3MF, and USDZ, plus 2D drawings as PDF, DWG, or DXF
- Prusa EasyPrint: Send designs straight to the slicer
Your designs, wherever you go
Everything you make on iPad, Mac, Windows, or iPhone stays in sync.
- Check a measurement at the hardware store
- Show the machinist exactly what you need
- Walk a client through your latest version over coffee
