## What is Facet?

Facet opens the 3D files your iPhone and iPad can't — instantly.

Tap an STL, 3MF, OBJ, glTF, GLB, PLY or OFF file in Files, Mail, Messages or AirDrop and it opens in a fast, beautiful viewer built on Metal. Models with millions of triangles load in a fraction of a second and spin smoothly at 120 Hz.

BUILT FOR 3D PRINTING
• Exact dimensions shown on screen, in mm, cm, m, inches or feet
• Volume, surface area and estimated PLA weight
• Watertight check that finds holes and non-manifold edges before you print
• Multi-part and multi-color 3MF projects from Bambu Studio, PrusaSlicer, Orca and others

INSPECT EVERY DETAIL
• Section view: slice through any axis to see inside your model
• Measure the distance between any two points, with X, Y and Z deltas
• Solid, Solid + Edges, Wireframe, X-Ray and Point display styles
• Front, top, side and isometric views, plus orthographic mode
• Bounding box, floor grid with soft shadow, and turntable mode

SEE FILES WITHOUT OPENING THE APP
• Real 3D thumbnails for your models in the Files app
• Interactive Quick Look previews in Files, Mail and Messages

SUPPORTED FORMATS
• STL (binary and ASCII)
• 3MF (including multi-file projects, components and colors)
• OBJ with MTL materials, textures and vertex colors
• glTF 2.0 and GLB with materials, textures and vertex colors
• PLY meshes and point clouds (ASCII and binary)
• OFF

SIMPLE AND PRIVATE
Everything happens on your device. No accounts, no subscriptions, no ads, no tracking — and nothing you open is ever uploaded. Your models live in Files › On My iPhone › Facet, so they're always yours.

Share a snapshot of any view, change the model color, switch between light and dark backgrounds, and get back to work.
