Embed 3D drawing in your iOS app.
The Graphite 3D SDK lets you drop the same AR modeling engine that powers the flagship app into any iPhone or iPad experience. Freehand strokes, precision bounding-box capture, live dimensions, STL / USDZ interop — behind your product's UI, tuned to your workflow. We're accepting applications for the current partner cohort.
What you can build with the SDK
Every app category below is one we've built enough of the underlying primitives for that the integration is measured in weeks, not quarters. If you don't see your case here, tell us in the application — the SDK's job is to be composable.
Real estate
Capture rooms at true scale. Listings, virtual staging, and instant floorplans from an iPhone walk-through.
E-commerce
Try-in-place for furniture, appliances, and fixtures. Customers place products at true dimensions in their own homes before checkout.
Interior design
Kitchen, closet, and bathroom planners with in-context 3D drawing. Sketch alongside the client, export straight to your design software.
AEC / construction
Spatial measurement and annotation inside existing design workflows. Import Revit / Rhino, mark up in AR at the site, export back.
Field services
Precise site documentation for insurance, inspection, and QA. Six-plane room capture with live dimensions, offline.
Games & creative tools
Spatial content authoring for AR-native apps. Freehand strokes, primitives, and precise 3D cursor inside your engine.
Museums & education
Interpretive layers annotated over physical spaces. Curators publish AR-first walkthroughs the visitor draws inside.
Manufacturing
As-built capture and comparison against design intent. Bounding-box measurement plus STL / USDZ interop.
What's in the box
Three families of capability, one Swift package. Each shipped in production inside the flagship app first — the SDK exposes them behind a small API surface designed for embedding rather than replacing your app's chrome.
Freehand strokes at any scale. Precision 3D cursor. Polyline, circle, rectangle, column, panel primitives. Pinch any shape to sculpt. The same tools shipping in the App Store version of Graphite 3D — headless, embeddable, styleable.
Six-plane and eight-corner room capture with live dimensions. Meters, millimeters, centimeters, inches, feet, yards. Delivered as clean geometry your app can measure, snap to, or export — not a mesh you have to clean up.
Import STL and USD at true scale. Export SceneKit (SCN), Stereolithography (STL), and USDZ. Works fully offline — the AR engine has no network dependency. Local peer-to-peer collaboration is available as an optional module.
Why invite-only
We're picking a small first cohort so we can give each partner direct engineering support during integration — shared Slack, weekly office hours, and negotiated feature timing where your product's ship date depends on it. Once the cohort is delivering, the SDK opens more broadly. If your team ships an iOS app and 3D modeling would change the shape of the product, tell us about it.
- Engineering support. Direct line to the team that wrote the code you're embedding.
- Feature negotiation. Genuine influence over what ships in the SDK during the cohort window.
- Patent licence included. Access to the underlying inventions on freehand AR drawing, precision cursor, angle-selective scaling, and pinch-to-sculpt.
- Early pricing. Cohort partners lock in below-market rates for the first two years.
