Hello Chad,
I have made some success this evening to the end goal of a PCB
with no parts and air flow holes spaced evenly between the two
copper surfaces. I did this by hacking an existing part from
the pcblib-newlib. Hacking means trying to deduce some aspects
of the format of a part and the "Pin" definition in a part.
I have a couple questions as result of my hacking and progress.
Am I correct that the pcblib-newlib is the current going
forward parts library and the other older libraries are for
transition time until all the parts from the older libraries
are in the pcblib-newlib?
Is the "Pin" attribute of the part "Element" a Via or just a
pin with hole for the layer the pin is assigned to? For example
I have created a part that is just the set of holes using the
"Pin" attribute of the part "Element" so the set of 6x3 holes
is spaced exactly as needed and with a home reference point.
The home reference point enables the set of holes to be placed
with ease all at once in exactly the same place on the copper
area rather than the challenge and time it takes to place these
18 holes one at time.
I will have more questions as I learn more for what I need to
accomplish.
