hehe
the whole idea behind gerber is that you cannot trace back the component name and pcb file
it is a manufacturing file containing nothing but captions (pictures) of the PCB layers . so you can view the gerber file , use it , duplicate it , but no modification or altering can be made , understand the point buddy ?? It is used to prevent u from reverse engineering and stealing somebody else's design , SO YOU CANNOT USE ALTIUM OR ANY SOFTWARE TO GET PCB FROM GERBER
HOPE that helps
