Understanding the Cylinder
A cylinder combines the properties of a circle (the base) and a rectangle (the side). It is the foundation for drawing arms, legs, trees, pipes, and many manufactured objects.

How to Practice
- Rotate the cylinder and watch the circular bases turn into ellipses.
- Observe how the degree of the ellipse (its "thickness") changes as it tilts away from you.
- Notice how the straight sides remain parallel even as the cylinder rotates.
Key Art Principles
- Ellipses: The top and bottom are perfect circles in 3D, but appear as ellipses in 2D perspective.
- Central Axis: Every cylinder has an imaginary line through its center that stays perpendicular to the major axis of its ellipses.
- Wrapping Lines: Use curved lines across the surface to show the cylindrical volume.
