Hi list,

Is anyone using Eagle to draw schematics and design a PCB? I just got
started with Eagle, and while I had enough experience with Orcad
Capture drawing schematics to get the schematic drawn, and the board
arranged, I'm not doing very well in creating or editing library parts.

One of my problems is the PWR labeling for the PIC18F2520 that I want
to use. It uses VDD and VSS for power, while the remainder of the
parts (EEPROM, MAX232 and some 74HCT595 gates) all use VCC and GND.
Now I don't care what you call 'em, but apparently Eagle does. It
dislikes connecting them together, and won't route them automatically
(well, not very well). And because of that, caps that I place near
the appropriate power pins of the packages don't get seen and
connected properly... At least that's what I think is happening.

I've actually spent considerable time in the manual and tutorial.
I've tried making a simple 8 resistor, 16 pin package, and although I
got through it, it looks terrible on the schematic (I know, try
again). If I could just copy one from the Bourns library, and change
the package out to a DIP, I'd have it. But although there is a way to
copy an existing library entry, I haven't figured it out. I couldn't
seem to edit existing parts either.

Can anyone help?
