While I shouldn't speak for Kai-Martin, I can offer some reasons that I and others have had for this. - you may have a preference for how they look. For example, I want my symbols to somehow represent what a part is instead of just being a box. Others may prefer a more compact box. - you may want to have a set of symbols which include the footprint name already (search for "heavy symbol" in the archives or wiki). Others may not want this. It is a personal preference thing and people tend to have strong opinions over which way is best. - you may want to build up a library of symbols that you personally have verified to be correct. I've been burned by trusting a library that came with a high dollar commercial EDA tool. Don't plan on doing that again. - you may have your own naming convention that you want to enforce - you may have a policy/desire on power/ground pins being explicit (i.e. shown schematically) or implicit (not shown schematically). - others ? What I tend to do is use the resistors and capacitors from the shipped library but largely use my own symbols for other components.. hope this helps. -Dan _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
