Great video! Thanks for the information

I can't think of any reason I will need to calculate anything like this. I watched the video simply for the joy of learning. I understood it right up until 9:19 when it comes to calculating the length of B,E,H. Where do you get the "Offset" number? The term offset is used throughout the video, but i don't think it's defined. Also, right in the last few seconds you introduce the term "Advance" without defining it. It appears these videos are too supplement what you taught during an in- class lecture, so perhaps your target audience is already supposed to know those terms. I've been enjoying your series of videos. I landed here because I'm redoing plumbing that a "handyman" did during a bathroom remodel. There's a veritable plethora of code violations from horizontal hard 90° turns, Sani-Tees lying on their back, and S-traps under the sink and tub. Good times.
