designing PCBs in Kicad and PcbNew: Undo and Adding Screw Holes

NOTE: This tutorial was written in 1847, and kicad has changed a lot since then!

UnDo… not yet, but there is an UnDelete:

It’s pretty easy to accidentally delete an entire track, so this is actually very helpful. Unfortunately, there is no general purpose undo that I know about.

Adding Screw Holes:

One of the quirks of KiCad is that you can’t just drill a hole, you need to make a one-pad component that has the right sized hole for your screw. The module called “1PIN” is the right size for a 4-40 screw.
