Am I hearing that the clip command may be the easiest way to do this? Or is
there a way to pull all the symbols in at one time with ref des assigned to
each individule component? I have done the clip several times but seems to me
there should be an easier way to do this. I just can't find any info on Modules
and 3rd party tools.
This is also something I want to do with power supplies. Design for re-use.
Thanks
Steve
