Creating depth with form lines

Learn how to transform flat sketches into solid, three-dimensional forms using simple contour techniques.

Flat 2D shape
Standard outline

Basic flat drawing

Drawing without form lines results in flat, lifeless shapes that lack depth.
Lacks spatial volume and weight
Hard to define surface orientation
Looks like a simple paper cutout
Visual depthZero depth
Needs improvement
