Augmented reality CAD for iPhone, iPad, and Apple Vision Pro. Create, edit, and explore spatial 3D designs wherever inspiration strikes. Now with generative 3D: describe an object and Graphite 3D can generate it directly in your scene. Turn text labels into editable 3D geometry, create objects using Siri, and use Siri or Shortcuts to resize selected shapes to precise dimensions. Design on a shared 3D canvas right in front of you. Draw while walking around your work, view creations from any angle, mark up interiors, plan at true scale, or block out objects as large as buildings. Capture photos and videos, then export your work to desktop CAD, modeling, animation, VFX, and game-development applications. Built for architects, interior designers, contractors, real estate professionals, urban planners, location scouts, VFX and game studios, spatial designers, curators, product designers, event teams, builders, property managers, and landscape planners. Graphite 3D is equally useful in civil engineering, environmental consulting, forestry, mining, forensics, archaeology, healthcare planning, and anywhere you need to think in space before something gets built. Features include: • AI-powered generation of 3D objects from text or spoken descriptions • Generate 3D geometry directly from labels in your drawing • Siri and Shortcuts integration for creating objects and resizing selected shapes • Generative AI renderings that transform spatial drawings into visual concepts • Solid shapes, extrusions, and Boolean modeling • Freeform 3D drawing • Live dimensions in millimeters, centimeters, meters, inches, feet, and yards • Precision 3D cursor • Object, point, line, surface, and angle snapping • Natural editing with Apple Pencil, pinch gestures, and spoken measurements • Full color palette • Focus mode • Topographic and site annotation • Animation paths for Houdini, Maya, Blender, and Unreal Engine • Building-scale, 1:1 editing • Local peer-to-peer collaboration • Core drawing and modeling tools that work offline • Photo and video capture • STL and USD import • STL, SCN, and USDZ export • Autosaved drawing library Sketch on the sidewalk before breaking ground. Test furniture in the room where it will live. Frame a shot before the crew arrives. Trace a gallery walkthrough across an empty floor. Walk a client through a renovation at full scale. Mark up a construction site with real dimensions instead of relying on a paper sketch. Or simply ask Siri to generate the object you need and place it in your scene. Free to start. Graphite 3D Pro unlocks additional professional features. Generative AI features use GenAI Credits and require an internet connection. Graphite 3D® is a trademark of Graphite Design Labs Inc.
