3D Model Viewer

Opens directly

• .glb — Best supported format. Geometry, materials, textures, hierarchy and animations all load.
• .gltf — Loads, but a .gltf file references external .bin and texture files. Upload the .glb version so nothing goes missing.
• .fbx — Binary FBX (7.x) loads with geometry and basic materials. Very old ASCII FBX and some proprietary shaders will not resolve.
• .obj — Geometry loads. Materials only appear if a matching .mtl and its textures are bundled — otherwise a neutral clay material is applied.
• .stl — Geometry only. STL carries no materials, colours, layers or object names by design.
• .dae — Loads geometry and hierarchy. Texture paths inside the file often break because they point at a local disk.
• .3ds — Legacy format. Geometry loads; materials are approximated and units are frequently wrong.
• .dxf — Opens as true CAD vector geometry with layers preserved. DXF is a 2D drawing exchange format, so it displays as accurate linework — there are no surfaces, materials or textures in the file to show.
• .ifc — Opens with a WebAssembly BIM parser: geometry, spatial storeys, object types and authored property sets all load. Very large federated models may take a while to index.

Needs an export first

• .dwg — DWG is a closed Autodesk binary format with no reliable browser parser. Save as DXF in AutoCAD (File → Save As → DXF) and upload that instead — nothing is lost.
• .skp — SketchUp's format is closed and has no browser parser. Export to GLB or Collada from SketchUp itself.

These are proprietary formats no browser can read. Export to GLB (or IFC to GLB) from your CAD application and the model will open with full fidelity.
