Free Online 3D CAD File Viewer

CCSOFTCZ provides a free browser-based 3D model viewer for engineers and CNC professionals. All file processing happens locally in your browser using WebAssembly — no files are uploaded to any server.

Supported 3D file formats

CAD geometry (STEP/IGES): .step, .stp, .iges, .igs, .brep — processed via occt-import-js (Open CASCADE Technology, WebAssembly)

Mesh formats: .stl, .obj, .ply, .off, .amf, .3mf

Scene formats: .gltf, .glb, .dae (Collada), .fbx, .wrl (VRML), .3ds

CAD-specific: .3dm (Rhino), .ifc (Building / BIM)

Note for Autodesk Fusion users: .f3d files cannot be opened directly — export as STEP from Autodesk Fusion (File → Export → STEP) before uploading.

How it works

Drop or select a file. The viewer renders it using Three.js with WebGL. STEP and IGES files are parsed by a WebAssembly build of the Open CASCADE Technology kernel (occt-import-js). Navigation supports orbit, pan and zoom. Edge display is available for precise geometry inspection.
