The IPC-2581 Configuration dialog is used to configure IPC-2581 exports. Related to the existing ODB++ format, IPC-2581 is an open-source standard developed by the Institute for Printed Circuits IPC-2581 Consortium in 2004, but since refined to the most recent Revision A and B releases (IPC-2581A/B).
