✈️ Why Standards Matter in Aerospace CAD
Aerospace projects face strict safety and compliance requirements.
CAD workflows must align with AS9100 quality standards and FAA/EASA regulations.
LOTAR (EN 9300 series) ensures long-term archiving of CAD and PDM data, keeping designs accessible for decades.
📊 Key International Standards
| Standard | Focus Area |
|---|---|
| AS9100 | Aerospace quality management systems |
| FAA/EASA Regulations | Aircraft certification and compliance |
| LOTAR EN 9300 | Long-term archiving of CAD/PDM data |
| ISO 10303 (STEP) | Data exchange between CAD systems |
| MIL-STD-31000 | Technical data packages for defense projects |
🛠Best Practices in Aerospace CAD
Parametric Design → Enables rapid iteration while maintaining traceability.
Topology Optimization → Removes unnecessary weight while preserving strength.
Digital Twin Integration → Simulates performance before physical prototyping.
Compliance-Ready Workflows → Automated checks ensure audit readiness.
Global Collaboration → PLM platforms allow engineers worldwide to co-design without data loss.
🚀 Essential CAD Tools for Aerospace Engineers
CATIA → Advanced surfacing, widely used in aerospace OEMs.
Siemens NX → Integrated CAD/CAM/CAE with digital twin validation.
