I do not know if the mailing list will automatically eMail me a reply. I have looked at the mailing list commands and options I cannot find if and how I may set if replies to me or others can be set. I am new to PCB software, but have reasonable average electronics skills over a number of years. I have a simple and unique challenge I have tried many different ways to figure out. I have done alot of internet searching, looked at many tutorials, and tried using PCB based on tutorials and my own exploring about PCB to find how I do this simple and unique PCB. I need to create a PCB that has a copper plane on top and bottom of the PCB. That simple. No components. It is likely via a third layer between the top and bottom copper planes I will want traces out to holes I may make as solder tabs or us a connector of some type. The reason for the trace connections as a third layer is to ensure the traces do not short with the aluminum parts metal part the PCB has to be mounted to directly at each end of the PCB. Then I will need to create a set of holes in the parallel copper planes area whose sole purpose is to let air pass between and not be a connection between the top and bottom copper planes. If I need to specify a PCB thickness then how I do so. So far I have not been able to find a setting/preference for the PCB thickness to do so. The how to do the connector and/or solder tab is not critical to the primary question. I will try to figure that out after I have the most important part of the PCB as noted above done in PCB. I will need to do a second PCB, but it will have lots of components on it. I would need to enter the schematic first of curse. I suspect I will manage with the help examples I have already read and will read again when I am ready to create a PCB from the schematic. If there is any missing part of the information to my core question of copper planes on top/bottom and holes in the copper plane that do not connect the top and bottom copper planes feel free to ask or comment on.
