There are two recommended approaches: neutral-format export (ODB++, IPC-2581) or direct Altium→Cadence transfer via intermediate formats (Exported Allegro ASCII or EDIF for schematic). Choose based on target Xpedition version and available import capabilities.

After translation, always perform these validation steps inside Xpedition Layout.
Altium frequently embeds absolute paths. Xpedition relies on variable paths (e.g., $CENTRAL_LIBRARY). Ensure your ee.ini or project configuration files are updated to recognize the Altium source directories.
Many engineers mistakenly attempt to use the ODB++ or Gerber intermediate formats. This is a catastrophic error for editable layouts.
