Drop a 3D model to view it

.stl · .obj · .ply · .glb · .gltf · .fbx — drop the .mtl + textures too for materials

How to use

  1. Drop a 3D model in — STL, OBJ, PLY, GLB, glTF or FBX. For OBJ or FBX with textures, drop the model together with its .mtl file and image files so the materials load too.
  2. Drag to rotate, scroll to zoom and right-drag to pan. Click a part in the view or the Parts list to select it, give it its own colour, and read its width, height and depth.
  3. Use Maximize to give the model the whole page; toggle wireframe, grid, auto-rotate and shading; then press Save PNG for a snapshot — all in your browser.

FAQ

Which 3D file formats can I open?

STL, OBJ, PLY, GLB, glTF (.gltf) and FBX. STL and PLY are common for 3D printing and scanning, OBJ and FBX are widely shared mesh formats, and GLB/glTF are the modern web 3D formats. Drop any one of them and it renders right away.

How do I keep an OBJ or FBX model’s materials and textures?

Drop the model together with its companion files: for OBJ, include the .mtl file and the texture images; for FBX, include any external texture images (textures baked inside a binary FBX load automatically). GLB and glTF already carry their materials. Everything is matched up in your browser — nothing is uploaded.

Can I colour individual parts and see their size?

Yes. Multi-part models list every sub-part in the Parts panel. Click a part — in the 3D view or the list — to select it; a colour swatch recolours just that part, and its width, height and depth are shown next to it. The overall model size and triangle/vertex counts are in the info panel.
