This statement that is tucked into Lesson 1's "Boxes: Additional Notes" section (https://drawabox.com/lesson/1/7/lines) kind of blows my mind: "The horizontal axis of an object, in this case a box, on which its horizontal vanishing points sit. When the box is set at an angle, this line tilts correspondingly." I'm new to drawing and have been letting it lead me where it will, in other words a not-very-disciplined approach to YouTube amd SkillShare tutorials, but I absolutely understand the importance of learning the fundamentals because I'm old and have enjoyed learning new things my whole life and know starting from the beginning is ultimately the best and fastest and least frustrating approach, so fundmentals are the place my interest has led me. And I have been led into a really trippy headspace thinking about perspective, which is still going strong thanks to the drawabox lessons. It's been interesting to say the least. But all that's just to say this: You mean to tell me all the boxes I have been drawing (before I even knew drawabox existed) from every which way that aren't parallel to the ground plane have different horizontal vanishing points? Oh my. That explains a lot...I think.
