im getting a few warnings in the log file when generating gerbers.
WARNING: more than one via class in film record
WARNING: Null REGULAR-PAD specified for padstack VIA188 at (-576.17 -530.00)
is it ok to leave these warnings alone?
There are skill programs avaliable that will automate the output (gerber, ipc356, nc etc). Take a look on the PCB Skill forum or write your own. There is also an OrCAD App called Release Manager that will do this for you.
