Hi all,
I have received Gerber files from my manufacturer that can't import them to Allegro? They are edited version of my Gerber files which I had sent them for fabrication. They have applied some modifications on them and returned them to me to confirm them. When I tried to import them into Allegro PCB I received an error message indicating the lack of art_param.txt file in the search path!. If put that file from my original generated Gerber files. I can't see anything after import:
