Three things a tutorial cannot do.
A tutorial hands you someone else's build to copy. This starts with yours. Same footprint, same walls: the roof gained structure and a darker slope, the gable gained a face, and the ground got finished.
Not on a second screen, and not something you pause and scrub back through. The plan renders in place on your own build. Cycle the options with the wand until one fits, then place straight through it.
Not a generic tip list. It reads the structure you are standing in, names the actual problem, and explains it plainly before it gives you the architectural term.
