A 3D compass, surely, follows the same rules as a 2D compass, right? Where between East and South is East-South, and between that and East again is East-East-South?
I'm trying to wrap my head around the "Inwards Diagonal UP line" in the pyramid shape. That would make it ZY or YX depending on its orientation, right? since if you were to move the object locked to that axis it would go diagonally?

I would say for stuff that is pulled inwards like that trapezoid it does so on all xyz axes on all four lines. They’re moving up which uses y, they’re being sucked in which uses z (depth) and they’re moving left to right because the form thins out towards the top. If you draw a vertical from the corner and another vertical from the arrival point you’ll notice that one saying zy has also moved along the x axis. I think. XD
Blender has the axes as kinda like monorail lines if you ever played rollercoaster tycoon. You can move the car left and right, up and down both under the ground and above it, towards or away from us. So a line at the back that’s pulled towards us is using depth just as much as one that moves away.
The toy plane wings are also moving in space along all three axes in my opinion because they want to kill me >.>

I may be punching above my weight with the object i chose, but i think i learned enough from it to be worthwhile!
A question for you!!!
How do you keep an organic shape like this proportional across the ortho views? I spent considerable effort in the beginning trying to use my tools to keep things proportional, but since its a weird geometric/ organic hybrid shape, i ended up needing to eyeball everything anyway!
The protractor is too curved, and the ruler/ squares are too straight, the paper trick helped when implemented with the top view, but it started to fail me once i moved to the oblique view.

I highly encourage you to try out one of the plans that Marshall included in the downloads section. It's manageably challenging, and you'll find that there are many creative ways to interpret simple shapes in the top view. Super fun exercise.
Projecting a curves is a great skill to have in your toolkit. I made this to show how to do a simple projection. The helmet will require more complex structures but this is the basic idea. It's a bit out of the realm of this assignment but I hope that helps!

If you came to me 10 years ago and told me my wish list would be full of books, id laugh at you. Ive been interested in The Einstein Factor for a while now.

Are there situations/subject matter that you cannot draw as orthos? The hand example is a good one - since the fingers are not ever really in a parallel alignment in hand poses, there will always be parts within the hand that are oblique view…and therefore in perspective/three axes…? I guess the room with lots of objects rotated randomly to each other would be another example. How would you approach these when trying to understand the object before jumping into putting into perspective?
If I'm understanding your question right, it sounds like you might be thinking too granularly about things. Orthos are just here to give us information so we can refer to it later. With complicated objects that are different on every side, like a hand, you would draw more views to show what is different about each of it's sides, one view for each side that is different. This works in reverse too, the treasure chest at 2:20 for example, only has a front, top, side, and oblique view. There is no bottom view, so we can assume its just flat on the bottom, or, if there was a hole busted out on the bottom of the chest, we would draw an ortho to show that.
If your question is instead about trying to keep proportions in orthographic views, you could always simplify the complex forms into simple shapes like we did a few lessons ago (i did my motorcycle), for a hand, you can use rectangles for fingers, which are much easier to draw in proportion :)

I'm going to try another item so i can use a ruler.

I found some time to watch the video of the assignment while trying it out on my own. This was a really fun challenge on learning about Orthros and One Point Perspective I must admit. I used my half circle ruler for this one on some spots since my name can be a bit tricky to spell out in drawing format. My name honestly though has had to have the most fun I ever had on trying to draw out in one point perspective. Especially when it came to the V and the E. I think I'm going to challenge myself with the 40 challenge throughout the next two weeks now. How can I get better with drawing out real challenging letters in One Point? I would like some pointers to practice learning later.
At risk of sounding generic, the best way to improve at letters you struggle with is to do more of them, keeping in mind the things were being taught here, and applying them.
As far as pointers go, be sure to draw both the horizon line, and a dot on the horizon line on your actual paper, not doing so makes it VERY easy to make things look off. I made an example to show what i mean:
- In example 1, the Vanishing Point was off the page, and i guessed where the lines would go using only my eyes.
- In example 2, i drew the VP and the horizon line on the page so i didn't have to guess where the lines would go, i just knew where they should've been.
- On the second image, i drew red lines following the edges of all the letters to show where they would connect. In example 1, every edge is going somewhere else even though i tried my best to guess where they would meet up. In example 2, even though i free handed it, the lines following all the edges of the letters all meet at the exact same spot (mostly).
Hope this helps, keep at it!

I took the opportunity to practice with my chisel pen after i was done
(its a 3.8mm Pilot Parallel Pen for the curious)
