solid-drawing-mastery

Solid drawing means creating the illusion of three-dimensional form, weight, and volume. In traditional animation, it meant understanding anatomy, perspective, and form. In digital motion, it means ensuring transforms and movements feel grounded in physical space, not flat manipulations of 2D shapes.

Form over symbol: Beginning animators draw symbols (a circle for a head, lines for arms). Master animators draw forms—volumes that exist in space with weight and dimension.

Construction consistency: Objects must maintain consistent volume and proportions throughout motion. A character's head shouldn't grow when they turn. A box shouldn't warp into a trapezoid.
