License lines are a necessity for sharing. Else, you'd have to put some license information in the environment of the share. >> * the footprint attribute is invisible > > Didn't change that either. Why would you like them visible? Because the footprint information can be scanned at a glance in the schematic. The footprint needs attention just like the value or the refdes. So it is convenient to have it visible by default. If I don't want to see the footprint attributes in finished design I can still hide them with "Hide specific text" in the attributes menu. In addition, the footprint provides a hint what to look for in the layout when I read the schematic. Else, a SO23 transistor looks the same in the schematic as a TO247 with cooler. > 200? Strange. Strange. Looks like 300 to me, except the output pin, > which indeed is 200. I didn't change that from the original symbol > either, though. "200" was just a typo by me... Somewhere in the documentation pin length 300 is recommended. However, nobody could give a reason for this value when I asked on this list. Since pins cannot be differentiated in print from nets, I decided to opt for short pins in my symbols. That is, 100 units, or sometimes even zero. > If it's not too much work, could you modify the 7400 symbol to your > likings and then send it back so I can modify the other symbols > accordingly? > See below. Except for the license, the symbol would fit into my collection of symbols in gedasymbols.org. I prefer the GPL as distribution license. As John Doty already pointed out, there is no hard right or wrong with many design decisions. I am, of course, biased :-) /------------------------ v 20100214 2 B 200 200 600 600 3 0 0 0 -1 -1 0 -1 -1 -1 -1 -1 T 500 500 9 20 1 0 0 4 1 & T 400 4100 5 8 0 0 0 0 1 device=7400 T 700 0 8 8 0 0 0 0 1 slot=1 T 400 2400 5 8 0 0 0 0 1 numslots=4 T 400 1600 5 8 0 0 0 0 1 slotdef=1:1,2,3 T 400 1800 5 8 0 0 0 0 1 slotdef=2:4,5,6 T 400 2000 5 8 0 0 0 0 1 slotdef=3:9,10,8 T 400 2200 5 8 0 0 0 0 1 slotdef=4:12,13,11 V 850 500 50 6 0 0 0 -1 -1 0 -1 -1 -1 -1 -1 P 900 500 900 500 1 0 1 { T 850 600 5 8 1 1 0 0 1 pinnumber=3 T 850 600 5 8 0 1 0 0 1 pinseq=3 T 750 500 9 8 0 1 0 7 1 pinlabel=Y T 850 450 5 8 0 1 0 2 1 pintype=out } P 200 300 100 300 1 0 1 { T 150 350 5 8 1 1 0 6 1 pinnumber=2 T 150 350 5 8 0 1 0 6 1 pinseq=2 T 250 300 9 8 0 1 0 1 1 pinlabel=B T 150 250 5 8 0 1 0 8 1 pintype=in } P 200 700 100 700 1 0 1 { T 150 750 5 8 1 1 0 6 1 pinnumber=1 T 150 750 5 8 0 1 0 6 1 pinseq=1 T 250 700 9 8 0 1 0 1 1 pinlabel=A T 150 650 5 8 0 1 0 8 1 pintype=in } T 200 1100 8 10 1 1 0 0 1 refdes=U?
