How to use the 3d model dimensions
- 1Open a modelDrop a GLB, glTF, OBJ, STL, PLY, FBX, 3MF, DAE or USDZ file. It stays on your device.
- 2Read the resultsStats appear instantly: triangles, vertices, materials, size and, for closed meshes, volume.
- 3Act on itResize, simplify or convert the model with the related tools below.
Tips for better results
- STL and 3MF are usually millimetres; GLB is usually metres.
- Use the STL resizer to set an exact size.
Units by format
- STL and 3MF: millimetres by convention (3MF stores the unit explicitly).
- GLB and glTF: metres by specification.
- FBX: often centimetres from Maya and 3ds Max.
- OBJ and PLY: unitless, so check with whoever made the file.
