I was just making some yesterday. It's time consuming if you use KiCad, which has a draw program with a UI from the 1990s. I could have drawn a footprint in Autodesk Inventor's sketch mode in a tenth of the time, and without having to use a calculator to compute distances from the data sheet drawing.

(CAD program UIs are really hard to do well. The big companies have it figured out at last, but the technology hasn't filtered down to open source yet.)
