I created several packages in a custom library to evaluate the Eagle Freeware version (limited to two signal layers). I have since upgraded to allow up to 6 signal layers.
I understand how to change the number of signal layers for the actual PCB editor through the Design Rules, but this does nothing for any existing library packages created in the Freeware Version.
How do you add additional signal layers to an existing library?
My current workaround is to simply copy all layers to a completely new package in a completely new library (that now shows 6 available signal layers), but this seems unreasonable. What now happens if I upgrade to allow up to 16 signal layers?
Sorry if I have missed something trivial.
