You mean I can just make a schematic on Eagle, press a button and vola! instant PCB design?
for simple circuits, yeap.
Eagle sometimes needs help figuring it out for more complex circuits. Eagle also doesn't account for current going through your traces, so I usually redo my power bus traces with thicker tracing.
It takes a little effort to figure out the non-intuitive interface, but its actually really easy to use.
woa that eagle CAD looks cool.
i read teh guide and it looks like you need to know some programming. true?
My tutorial explains 90% of the coding you need to do, and I linked to another tutorial to explain the rest. Coding is only needed if you use a component that isn't already available for Eagle3D, or has a different name than in the library. There is a good chance you won't have to code . . .
