That is such a wonderful but hard exercise. I dived in the 1st two for now but already got carried away while doing level 2...completely forgot the assignment guidelines... I will definitely do more and try doing the level 2 the right way. This exercise tackles my biggest weakness (basic 3d shapes orientation), so thanks a lot for these, it’ll be definitely helpful (it already has started to be). I hope that with practice i’ll finally get those box in the right angles
