The formats people actually have on their drive — from the web's glTF standard to the FBX files Maya and Unreal ship.
The web's standard for 3D — meshes, materials, animation, packed into one file.
Most commonEditable glTF with external textures. Common output from Blender, Sketchfab, and most engines.
Text-basedThe interchange format for Maya, Blender, Unreal, Unity. Rigs, skinning, animation tracks.
Industry standardThe lingua franca of 3D printing. Triangle meshes, nothing else.
3D printingThe 35-year-old standard everything still exports to. Mesh plus optional MTL.
UniversalPoint clouds and scans, often from photogrammetry or LiDAR.
Scanner outputSTL's successor — color, materials, and print metadata, all in one file.
Color printSketchUp, Daz, older Blender. Meshes, materials, and skeletal animation in XML.
Legacy interchangeAutodesk's original mesh format from the DOS era — still hanging around in asset packs.
Vintage2D drawings and 3D entities. Floor plans render top-down, 3D entities render in orbit. Lines, arcs, splines, blocks.
CADB-rep CAD interchange — SolidWorks, Fusion 360, CATIA. Tessellated in-browser via OpenCASCADE.wasm. Also opens .stp.
CADOlder CAD interchange standard. Surfaces, curves, B-rep solids. Same OpenCASCADE backend as STEP. Opens .igs too.
CAD legacyNot features for a deck. Features you'll use the third time you open a file.
The viewer is a static page. There's no server to upload to. Disconnect your wifi after the first load — it keeps working.
Real units. Real geometry. Useful for checking dimensions before you slice for print.
Three ways to look at the same mesh. One keystroke between them.
A draggable plane reveals interior geometry — wall thickness, voids, hidden ribs.
Studio, sunset, overcast, night — see how materials actually behave under real light.
Switch between mm, cm, inches. The floor knows what it is.
Manifold check, normal flips, minimum thickness. Before you send to the slicer.
Press S for a still. Press G for an orbit.
If you open 3D files often, the apps add file associations, offline access, and AR on iOS.
