This is my first Eagle project, I am new to pcb design.
Can someone tell me what the best way is to save a project before routing?
I have completed my schematic and placed all my components on my board. This was very time consuming
I want to try routing a few different ways, including manual and auto, and want to be able to go back in case I mess something up.
I will try a 2 layer configuration first, but might need to use 4 layers.
I know that cntr Z goes back one step, but not sure how many steps I can go back with it.
I had an issue before were I lost my back/forward annotation and had to start over again with the layout. Don't want this to happen again.
Thank yo for your help.
