Drop a 2D DXF drawing or 3D CAD and mesh file — it loads directly in your browser. Nothing is uploaded to a server.

Drag & drop your file here

or click to browse

Choose file

.dxf · .step · .stl · .iges · .obj · .gltf / .glb · .ifc · and more

Models made of several files (.gltf + .bin, .obj + .mtl + textures): select or drop all files together.

For Autodesk Fusion files (.f3d): export as .step from Fusion first

Files are processed locally in your browser — nothing is sent to our servers.

Unsupported format or corrupted file.

Free online 2D and 3D CAD file viewer

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

Supported file formats

2D drawings: ASCII .dxf — lines, polylines with bulges, arcs, circles, ellipses, splines, text and inserted blocks

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

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

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

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

How to use it

Drop a file anywhere on the page or choose it with the button. In 3D, rotate with the left mouse button, pan with the right button and zoom with the wheel. In DXF drawings, drag to pan and use the wheel or a two-finger gesture to zoom. Use Fit view to reset the view. Models split into several files (a .gltf with its .bin, an .obj with its .mtl and textures) load correctly when you select or drop all the files together.

Opening Autodesk Fusion files

Fusion's native .f3d / .f3z format cannot be opened in a browser. In Autodesk Fusion choose File → Export, set the type to STEP and open the exported .step file here.
