CATIA File Tools: CATPart/CATProduct Viewer & STEP Converter

Open CATIA V5 CATPart and CATProduct files online, troubleshoot missing assembly references, verify geometry and convert supported models to STEP.

This hub collects CADProps workflows for CATIA V5 CATPart parts and CATProduct assemblies.

Use it for browser inspection, assembly dependency troubleshooting and neutral STEP handoffs.

Open CATPart and CATProduct files

Use the CATIA viewer for supported CATPart files and packaged CATProduct assemblies.

For CATProduct, include referenced CATPart files and preserve their relative folders in a ZIP.

Convert CATIA to STEP

Use the CATIA to STEP converter when the receiving workflow needs neutral geometry.

Verify the output rather than relying only on a conversion-success message.

CATPart guides

CATProduct assembly guides

A CATProduct can render partially even when referenced CATPart files are missing. Keep incomplete status visible with all calculated properties.

Version and scope checks

CATIA native compatibility can depend on the source release and actual data type.

When a file fails, confirm:

Neutral exchange versus native editing

STEP is useful for cross-CAD geometry transfer. It does not recreate CATIA's original sketches, product links or feature history as native editable data.

Keep the original CATIA package when future native work matters.
