Hi, This software is relatively intuitive, but as I'm not a professional there are a few things I'm unsure of. I was wondering if all layer shapes on a particular layer have to be 'grouped' in some way?, or "if it's blue, it's copper" sort of thing? If my top silk layer is partially obscured by blue copper shapes, will it still print on top? I have all these DRC errors but I'm not sure exactly what they mean...I have aligned everything. Am I right in assuming the manufacturing is done from independent files according to what needs to be done to the board and this file is split up for that? PLease forgive the stupid questions but I just don't know how the process is done. Rgds, Mark
