How to solve pin being overwritten by more than one signal errors in EAGLE PCB CAD?

Hi Mohammad,

I'm not sure what you did, but it could have occurred perhaps if the supply symbols were renamed. By the way, some tutorials for EAGLE are not great, they have errors.

Anyway, to learn, there is an excellent tutorial series here, and it is entirely accurate. Link to part 1 is below, and there are links to the remainder parts there too if you follow that link.

Hi,

I am relatively new to EAGLE and PCB Design. I am watching an online course and the tutorial goes through designing a PSU.

There are some errors that will be fixed later as the instructor informed. But I am facing these highlighted errors. That don't occur in the tutorial.

 

Can someone explain step-by-step on how to solve and why it happens?

Probably you placed a supply symbol (GND in this case) onto an existing

net (i.e. you drew the net first an then placed the supply symbol). If

you do that EAGLE asks you if the net should be renamed (to GND in this

case). Except for very rare special cases you should answer "yes" to

this question, because if you say "no", the net (and in your case the

capacitors) won't be connected to GND.

To fix these errors, just rename the nets in question to GND.

And please use eagle.support.eng for questions like these.
