What is a .CL3 file?
CL3 is a terrestrial laser-scanner point cloud from Topcon scanning systems.
- Did you know
- CL3 stores the dense point clouds captured by ground-based Topcon 3D scanners.
- Topcon’s CL3 is an indexed point-cloud format, the processed counterpart to the raw CLR file straight off the scanner.
- Autodesk ReCap can read CL3 directly, keeping each individual scan position so surveyors can register the clouds together.
- What Analyser reads
- Identify more 3D, CAD and scene files: Google Draco compressed meshes, Gaussian splats (KSplat), Universal 3D, Dassault 3DXML, DirectX .x models, Qubicle voxels, Wings3D, Autodesk Revit (RVT/RFA and templates, build version from BasicFileInfo), Siemens Solid Edge, Navisworks, legacy CATIA V4, terrestrial-scanner point clouds (FARO/Trimble) and legacy binary Visio (.vsd).
- Depth of analysis
- .CL3 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .CL3 file
- Drag a .CL3 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
