[PCB_FORUM] Re: Is there a way to step and repeat placement for identical circuits on the same PCB?

Hi Jean-Charles,

I'm only copying clines, not vias.  I have four BGAs, and I routed one, and
tried to copy the clines (top layer) and got the error.  But...I can copy
the clines on the inner layers, as they are connected to vias.  So, it has
something to do with pads/pins vs vias.

Regards,

Austin
