Impedance data

Question asked by rpashfo on Sep 10, 2014

Using Expedition PCB is there an automated way to uniquely identify impedance controls to the fabricator? (Value, width, layer) Use of unique trace widths and notes on fabrication drawings is what I want to avoid. Possible use of IPC-D356B from Fablink XE? Is IPC-2581 an option from Expedition?
