Using ASCII Conversion to Import Without Allegro
An Altium Designer workstation that does not have a licensed Allegro installation is able to import Allegro ASCII Extract files (*.alg). The following procedure enables a Licensed Allegro user to convert Allegro binary *.brd files to Altium compatible *.alg files. The conversion must be run on the Allegro licensed machine.
1.Locate the following two files in the \System folder of your Altium Designer installation (Summer 08 or later):
a.Allegro2Altium.bat
b.AllegroExportViews.txt
2.Copy the two files to the folder containing the *.brd binary Allegro version 15.2 or 16 file.
3.Open a command prompt, navigate to the folder containing these files and type the following: Allegro2Altium your_file.brd
4.Surround your filename with double quotes if the filename contains spaces, i.e.: Allegro2Altium "your file.brd"
5.The ASCII file is now created in the folder. Copy the *.alg file to the Altium Designer workstation, Summer 08 (Version 7) or higher, and import using the Import Wizard.
