Basic Drawing Introduction

Types of Lines

• Vertical lines: are straight up and down and perpendicular to horizontal lines
• Horizontal lines: are straight up and down and perpendicular to vertical lines
• Diagonal lines: are lines that straight in any direction except vertical or horizontal
• Zigzag lines: are a series of diagonal lines joined end to end
• Curved lines: are lines that bend in any amount of degree; they may be gently wavy to tightly wound spirals

Common types of line drawings

Contour line drawing: Drawings that use a fairly continuous line to represent the edges and surface detail of shape or objects being drawn

Gestural line drawing: Drawings that use quick pencil strokes (or other drawing instruments) to capture a scene. Gestural drawings imply action and movement

Hatched and cross hatched line drawing: Drawings that consist or parallel lines (hatching) or crossing parallel lines (cross-hatching) drawn to create changes in lightness and darkness and texture.

Shape:

There are two general categories that are used to describe shapes. Geometric and Free-Form or Organic Shapes. Examples of geometric shapes are: squares, rectangles, triangles, circles, oval, and pentagons and so on.

Volume is a three-dimensional form comprising length, width, and depth. Three-dimensional forms contain points (vertices), lines (edges), and planes (surfaces). A mass is the two-dimensional appearance of a three-dimensional form
