Hi everybody,
I don't understand why there are a pair of layers with the same name:
xxCu and xxCmp. Which is the use for each one?
I am confused about layers too especially as I am trying to do a single sided PCB layour. As far as I can make out there are always at least two copper layers - the one on the bottom xxCu and the copper on the top or component side xxCmp. All other copper layers are inner copper layers and labelled as such. Trying to get the autorouter to route just on the copper side only is quite hard.
... and the utility of the layers ECO1 and ECO2?
According to the help ECO1 and ECO2 are general layers for anything you want.
