How to make a custom library part in Eagle CAD tool

Step 16 Draw the symbol

Use the wire tool to draw a box that will represent the symbol on the schematic. By default you will be drawing on the symbol layer. Double check to make sure by looking in the upper left corner after the wire tool is selected. The layer drop down menu should have "94 Symbols" selected.

Once the box is drawn, type "pin" in the command window, and start placing the 32 pins evenly around the box.

It's probably a better idea to just make a tall, skinny box with pins in columns on the left and right sides. It's more compact and easier to use with Eagle's weird wire drawing tool which always assumes the horizontal component of the wire comes first (changing this behavior by right-clicking through every possible style or using the tool-bar becomes tedious quickly).

Also, the perfectionist in me cringes at your box being just off the visible grid, but that's neither here nor there ;-)
