IGES Sample Files
IGES (.iges, .igs) files are a long-standing CAD exchange format for surfaces, wireframes, and manufacturing-oriented geometry handoff. Use sample IGES files to validate legacy CAD import paths, surface translation, and compatibility across design and production systems.

IGES Testing Workflows
Use the file table first, then branch into compare or FAQ only if the task needs more context.

Checksum Verification
Use checksums to confirm file integrity after download.
shasum -a 256 your_file_name_here
# Compare output with SHA256 values listed above.
Where is the machine-readable manifest?
Use the manifest when you need stable names, SHA256 values, and URLs for automation.
Use in code — curl, Python, Node, wget
Copy any snippet directly into scripts, test suites, or CI pipelines. All URLs are stable and publicly accessible with no auth required.

Validation Methodology
- Validate extension and MIME detection before processing.
- Benchmark performance with small and larger files.
- Test malformed-input handling and error messaging.
