CGR is a CATIA Graphical Representation - a lightweight, view-only version of a CATIA 3D model that shows the shape without the full parametric data. CGR files let huge CATIA assemblies be opened and reviewed quickly, because they carry only the visible geometry, not the engineering history. Analyser handles .CGR alongside related formats such as .ABC, .AFL, .ARX and more. In Analyser's format library, .CGR sits in the System & disk category.

How do I open a .CGR file?

Drop a .CGR file onto Analyser at https://lab.valjdakosta.com/ and it is identified directly in your browser - no upload, no account and no software to install. A catch-all for rare and niche formats Analyser still identifies from their bytes: 3D caches and scans (Alembic ABC, FARO FLS/FWS), camera and design data (ARRIRAW ARX, Capture One masks, CATIA CGR), JBIG codestreams, firmware dumps (Binwalk), draw.io diagrams, OptimFROG DualStream audio, RTTTL ringtones, LaTeX style and class files, Sun Raster and Truevision TGA images, MPEG-2 streams, PVR/DVB recordings, Tiled tilesets, Windows Prefetch and Reaper project backups.

Can I open a .CGR file online for free?

Yes. Analyser is a free online .CGR identifier that runs entirely in your browser - your .CGR file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What Analyser reads: A catch-all for rare and niche formats Analyser still identifies from their bytes: 3D caches and scans (Alembic ABC, FARO FLS/FWS), camera and design data (ARRIRAW ARX, Capture One masks, CATIA CGR), JBIG codestreams, firmware dumps (Binwalk), draw.io diagrams, OptimFROG DualStream audio, RTTTL ringtones, LaTeX style and class files, Sun Raster and Truevision TGA images, MPEG-2 streams, PVR/DVB recordings, Tiled tilesets, Windows Prefetch and Reaper project backups.
Depth of analysis: .CGR 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 .CGR file: Drag a .CGR 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.
