FreeCAD, Common sticking points for beginners in tutorials!

I'm looking to increase the amount of beginners FreeCAD content on peertube/makertube and so this is a first very quick video, hopefully the first of many. I've noticed, having written a [free to download book ](https://magazine.raspberrypi.com/books/freecad), written lots of blog tutorials and produced lots of tutorial videos, that there are some common mistakes I make occasionally in tutorials that can really stump people trying to learn. Some of these are common in other video content so I thought I'd do this "things to watch out for in FreeCAD tutorials" video!
