in the schematic, before converting to a PCB board, what do we do with the pins that we want grounded?

[James Lewis]

Create a wire connected to the pins. (The wire does not need to be connected together). Use the NAME command to name each of those wires "GND".

Thanks! this was very usefull, I have a question, say I have a portion of my board where I want the spacing to be larger, like input conectors with higher voltage.

Can I have different spacing within a ground polygon? Because there are some areas that become isolated from ground if I choose a bigger spacing. So i would like a bigger isolation just in certain areas of the board.

[James Lewis]

The only way that comes to mind is using multiple polygons, instead of one giant GND polygon.

Would this circuit work fine without the ground plane?

[James Lewis]

Ground planes are like decoupling capacitors. They help with things you don't realize you need help with, until they aren't there.

Thank you very much!

Glad it has been helpful. Please let me know what else I can help explain.
