What is the proper zero orientation for a SMT LED?

According to IPC-7351, the cathode should be on the left for a molded diode. Echter, when I use component wizard of my suppliers to create a diode, it places the cathode (K) on the right. Does it depend on the manufacturer? How does the assembly house know which way is correct?

Wanneer u een PCB wilt maken, welke informatie moet worden verstrekt aan de PCB-fabrikant?

I am a mechanical designer. I have sent my PCB design file to manufacturer. But they said the data may be not enough. So what data are you used to send to your PCB manufacturer.

Does each process have its own PCB or there is just one?

To my understanding, each process in the operating system contains its own separate Process Control Block. Can someone explain this to me. Does each process have its own PCB or is there just one PCB that contains all the information for all the processes?
