About This Tool

CATPart Viewer operates as a focused data tool for CAD geometry assessment. It accepts CATPart and common CAD formats via upload and returns machine-readable metadata such as bounding box, volume, and centroid. By normalizing units to millimeters and providing export options, it supports PLM, ERP, and BOM integrations. The tool is designed for engineers, procurement teams, and project managers who need reliable geometry insight without launching a full CAD environment. It emphasizes accuracy, traceability, and scalability for large parts and multi-file workflows. The metadata can serve as a backbone for design reviews and interoperability with downstream systems, reducing manual data entry and risk of dimension mismatches. Advanced options allow inclusion of additional metrics if material data is supplied, enabling basic mass estimation when density is known.

How to Use

Upload a CATPart/CAD file and set optional unit preference.
The system detects units and parses geometry data from the file.
The tool computes bounding box, volume, and centroid, then assembles metadata in JSON/CSV format.
Review the results and export as JSON or CSV for downstream systems.
Integrate the metadata into design reviews, BOM preparation, and supplier data exchange.

Frequently Asked Questions

Find Quick Answers

Which formats are supported?

Supported formats include CATPart, CATProduct, STEP, and IGES. The tool focuses on geometry metadata extraction and does not provide full CAD editing capabilities for unsupported formats.

How is volume calculated?

Volume is calculated via mesh/geometry integration where available, with fallbacks for simplified bounding approaches on partial data. Hollow or complex internal geometries may yield approximate results and are flagged when accuracy is limited.

Can I export results?

Yes. Results can be exported as JSON or CSV after calculation. Exports preserve key properties (bounding box, volume, centroid, units) and identifiers for traceability.

What if the file is corrupted?

If parsing fails, the system returns an error flag and partial geometry data if recoverable. Incomplete metadata is returned with guidance for remediation and re-upload.
