First post. Nick, fantastic videos and you are an inspiration. I am puzzled about something though, your dimensioning style. I've never seen anything like it. But I see the advantages immediately. Is this your own invention, or something you learned at RISD? I'm used to dimensioning to structural grid lines for columns and such, but you seem to have a system of reference grid lines tied to key jogs in your buildings. Then I suppose you tie intermediate dimensions within those where need in the plan. Certainly makes the drawings look very clean. No more stacked dimension lines around the perimeter (I've had them 5 deep at times). Just curious about that. Can't wait for the book. My wife is getting tired of listening to you in bed while I watch and rewatch the videos on my Kindle...
