Designing Circuit Boards with EAGLE: Make High-Quality PCBs at Low Cost

Chapter 10. Editor Commands

At this point, you’ve learned a great deal about designing circuits with EAGLE, from defining a schematic to routing connections to generating artwork files. All the interaction with EAGLE has been accomplished with point-and-click operations, and this is fine for simple designs. But when designs have hundreds or thousands of components, mouse clicks become tedious and error-prone. For this reason, EAGLE makes it possible to automate operations using editor commands.

The syntax of these commands is easy to grasp. For example, the command MOVE U3 (2.5 3.5) moves the origin of component U3 to the position (2.5, 3.5). But it takes time to become familiar with all the new commands and their arguments. It’s time well spent. ...
