I made a note, but I didn't buy. Now I have
bought (not without difficulty, but that's life).

be a reference for the various questions.
Would that I had your depth of

Exactly so. I include mechanical
things like fixing holes, RF screens, and the PCB itself

A hole is just a single pad of the

hole).?? If it has copper layers, they can optionally be
connected to
any net (usually the ground plane, and typically with no
thermal
spokes).?? In the past I just defined the hole on the
schematic with a
single pin connector, but these days I have my own
symbol.?? Often the
associated footprint that I create will define a board
outline and all
the holes (as pads), and typically much more (such as
silk screen
elements).?? I routinely import that from mechanical CAD
as a DXF.
So there are no hard and fast rules - you just do
whatever cranks your
tractor on the day.
