I started making these SketchUp, Adobe, Autocad, Esri, (etc.) videos as supplemental material for university classes I taught. Eventually the videos became the core material and the classes became supplemental. I was applying a "flipped" classroom methodology without even knowing that was a thing. Another evolution in my videos is that I gradually made them less specifically for my students, and more for "anyone who might stumble across them". The more subscribers and compliments I received, the more consumer-agnostic I made the videos.
I decided to take a break from university teaching, but that doesn't mean I will stop making videos. I actually hope to make more now! Feed me with your SketchUp/AutoCad/Adobe/Esri questions. That is my video-making fuel!
