Thanks for the reply. Just for a better understanding,
say I have two pins U1.1 and U1.2 are supposed to be connected to the two input pins of a NOR gate: U2.1 and U2.2. (e.g U1.1 to U2.1 and U1.2 to U2.2),
of course it would also be right if U1.1 is connected to U2.2 and U1.2 to U2.1. (U1.1 and U1.2 swap)
by sectioning U1 -> "fixing" U1, U1.1 will be mapped to U2.1 and U1.2 to U2.2 when the schematic is exported to PCB Editor (re-packaged).
am I right to interprete like this?
