The importer supports OrCAD.max PCB files, but I understand that format is no longer used with OrCAD 16.x and OrCAD 17.x. Both generate.brd PCB files with either the reduced or full versions of the Allegro PCB Editor. The Altium Designer documentation states it supports importing Allegro.brd and.alg PCB files. Open Allegro and select - Setup User Preferences Choose the Paths + Library category and set your padpath and psmpath to point to your current working directory. Click Expand if it isn't selected. At the top of the padpath list choose New (Insert) and place a '. ' (period) as the Directory name. Too many files: OrCad/Allegro exports all files in the same directory as the.brd file, including a lot of log files. Just trying to find all the manufacturing files can be a pain so please don’t send all of this to the fabricator.

To convert a printed circuit board from an ALLEGRO CAD system, the database must first be extracted as an ASCII file using the CADENCE ALLEGRO Data Extract utility which is controlled by the Test Expert script file. The Test Expert script file describes the data to be extracted from the database. For Backannotation, the same OrCAD and Allegro PCB Editor program (genfeed) is used to create the OrCAD and Allegro PCB Editor output files. These files are then read by DE CIS and used to update the schematic to reflect any changes made to the design by OrCAD and Allegro PCB Editor (pin and gate swapping, reference designator changing and so on).
