I am working with Eagle 5.0.0 and I am facing two problems.
- The first one is that I cannot add a new layer. I need 6 layers, but it shows only 4 on the Display even when I set in the Design Rule the equation (1*2+3*14+15*16) or (1*2*3*14*15*16);
- The second is that I have another design where one of the layers is a microstrip structure (just a polygon) and I have to use the same on the new board I am designing now. However, I am not able to export from the old layout to my new one. How can I do that?
