Schematic not showing all pins on device

Question

Hello, I am attempting to use the 74LS373N DIL20 device in the 74xx-us library that you can download from Eagle. When I add the device to schematic, it shows all pins, except 10 and 20. I have included pictures to demonstrate what I'm trying to show as the problem. There are two schematic symbols that are supposed to show up when you add the device to schematic, the data pins, and the power and ground. It doesn't show the power and ground pins. Can anyone tell me why this is happening? Thanks, -Eric

Hi Eric,

it is possible to create devices that consist of several symbols and you can decide how to place them in the schematic (Addlevel). Lot of devices have the power pins hidden. To get them visible in the schematic use the INVOKE command (it's represented by an icon that shows kind of four gates) and click onto the symbol (or type in its name in the command line). Now you get a table with available gates you can place.
