I struggled with maintaining proportions of the foreshortened views. Also, the hemisphere on top and the cone in the front are pure guesses. I don't know how to construct them in perspective.

Fun assignments

I don't know how the tilt of a box affects the angles of the converging lines - anyway, the horizon line helped me while constructing the airplane.

I have a bit of an odd question. I do okay with references and I love foreshortening. But after a lot of practice/observation I still cannot draw right angles correctly from imagination and intuition. Is it normal at this point in the course even after tonnes of practice and observation? When I don’t have a box in memory, my boxes slant terribly. It’s the z axes perpendicularities I mess up the most grievously, even though I have many boxes from observation under my belt. With wonky boxes come unstable scaffoldings. Am I expecting too much of myself this early in? As we keep going I imagine stuff will clarify with mileage but this is nagging at me still. I attached some examples.

thank you for the lesson! This is what I'm missing when doing the arrow assignment. Will do the 3D Model Airplane for the next one
