If you are aware of it, you can control it! And you will draw better cubes :). In reality, cubes are rarely this even and flat! As I turned my model cube around, I had to constantly remind myself to double-check what I am actually seeing. We learned it as a box that looks something like this: The reason is because our brain tries to straighten the cube in our mind, makes the angles flatter and more even. When looking at a cube that is turned or tilted, it’s hard to actually “see” how to draw it.It’s easy to see the errors, when they are side by side. Put the paper right up to your reference cube and compare with the lines you’ve drawn.Then you can judge the angle you see in comparison with the vertical of the plumb line. Here is an article that explains measuring techniques in detail. Or use a plumb line (a weight on a string) that will show you the perfect vertical line. You can also use a string instead of a pencil. Align the pencil with the cube side, and then transfer the same angle onto the paper. Use your pencil to check the angle of each side.
If you get the angles right, the cube will look solid and convincing.
A cube drawing is defined by 3 angles, one for each side.Maybe with some practice it will become easier… but for now I will use a reference. That’s why we have them! It’s devilishly hard (at least for me) to visualise a cube in space without actually looking at it. When in doubt, use a box for reference.Not all the stars are even, but it’s ok! It’s all part of learning 🙂 Techniques for Drawing Solid and Convincing 3D Cubes I filled the page with stars and colored around them.
