Next question: I have a design made using Mentor Expedition (EE7.x) that I want to import to my Allegro installation.
From what I can see, the Import tool in Allegro is from Mentor Board Station (nets.nets, comps.comps, (etc)).
Which means: Not to be used with Expedition...
But if I am wrong, then do I need to do an ASCII-Out in order to proceed? (I do not want to reinstall
the EE7.x software, and I do not know if this procedure is included with Expedition)
You are correct, Allegro 16.5 can import Mentor Boardstation or PADS but not Expedition. You would need to talk to a third party translation company to get an Expedition file into Allegro.
