I am familiar with Proteus software and have designed my PCB with its ARES package. Now I want to order it and found a company that offers good price but they only accept PCB layouts in .PCB format. They said I have to design it with Protel ( I think they meant Altium Designer ?) but I am not familiar with it and don't want to buy a new software package and also it may be so time consuming to start designing from the beginning. Is there any way to convert the file made by ARES (.LYT) to .PCB ?
I am so sorry if I mentioned the formats incorrectly because I don't know much about softwares other than Proteus !
