Hi, thank you very much for reviewing my homework! I understood everything and I'll try to fix those mistakes going forward.
As for the cart thing (it's an ash tray :3), I took some creative liberty with the approach as I was pretty confident it would work. Instead of using one box, I used two boxes for the two major masses that are present because I don't think one big box would serve a purpose in this case. I wouldn't gain a meaningful landmark with its subdivisions and it would also not help me when determining the position of the top part. The approach I used is better here because I have the knowledge that the ash tray can close and open with the pivot point being the cylinder in the back. Using this information, I know that the top box has to rotate on a circle (ellipse in 3D space) that has the center point on that cylinder. This curve right here is part of that larger cylinder. It's a consistent way of getting the relation of the top and bottom part of the ash tray correct. I eyeballed the size of the top box by guessing how much bigger it is in relation with the bottom box. I dunno how you would calculate that correctly lol.
For the spherical objects, I just placed them into boxes as much as I could. That didn't work so well in the second picture, as the object was pretty weird. I realized too late that my approach could be better here. If you look closely, you can see a triangle in there, I think that's the way to tackle the position of the "legs", but I added it too late here so it had no effect. I had to search up how to place a perfect triangle in a circle and I already forgot how. Anyways this was a complex subject, most circles/ellipses in 3D space can be confronted with this method from lesson one, but applied on subdivided planes multiple times (one for each edge/landmark of the spherical object, then connected at the end).
I was actually in the process of making those 5 critiques, but you were faster haha. I heard that you could also upload the same lesson as many times as you want (as long as you wait a week in between) from Uncomfortable himself, so I decided to try both ways.
