A professional CAD data management system centralises files within a secure vault, controls access and streamlines workflows. It eliminates issues with lost data, duplicated files and inefficient folder structures. Engineers benefit from faster searching, structured approvals, version control and reliable revision history. Collaboration improves through controlled access, automated notifications and shared viewing tools. PDM enhances change management, supports regulatory compliance, and reduces errors during manufacturing by ensuring everyone uses the correct, approved data. The system increases efficiency, protects intellectual property and provides a scalable foundation for organised engineering processes.
