Essential Eagle Skills
Some things to note working with pads and parts in Eagle:- Zooming in and out: If you have a scroll wheel on your mouse, scroll to zoom in and out. You'll do a lot of this in Eagle, so it's good to get used to it when placing and updating parts and working with PCBs, or zooming in on details regions where you need to do some work.
- Rotating parts and pads: Right-click the active pad to rotate. You'll do a lot of this 'select-then-rotate' when placing parts on your PCB or designing your packages.
- Use that grid: Notice that the pad moves based on the grid that we defined previously
- Also notice that pads rotate and are place around their center point. This is important when placing parts, since you need to calculate and enter it's exact position, which is based on the center of your pad.
