One of my favourite woodworking Youtube guys just put up a lengthy tutorial on Sketchup basics for woodworking. Could be useful for those with no CAD experience but want to get started.
Personally I'm used to an AutoCAD/Inventor world so Sketchup drives me nuts a bit, I've been using Onshape for any mockups that I do and find it does what I need quite well. Fusion360 is pretty okay too, but you need to download an app where Onshape just runs in a browser which is extremely convenient. If Fusion360 would just run in a browser I'd probably use it instead, as it behaves like a very slimmed down version of Inventor.
