Explain and demonstrate basic sketching skills and techniques.

sketching concepts

Sketching Concepts

2.01

Explain the concepts related to sketching.

purpose of a sketch
Purpose of a Sketch
  • Quickly & easily get an idea on paper
    • Design sketches
    • Freehand technical sketches
    • Technical illustrations
sketching materials
Paper

Pencil

Soft lead

Optional

Eraser

Grid Paper

Sketching Materials
sketching technique
Sketching Technique
  • Proportion
  • Clarity
  • Sketching Aids
sketching lines
Sketching Lines
  • Vertical lines
    • Top to bottom
  • Long straight lines
    • Series of short straight lines
sketching circles arcs
Sketching Circles & Arcs
  • Begin by lightly constructing a square
sketching angles
Sketching Angles
  • Begin with 90°angle

45°

60°

30°

Subdivide once

Subdivide twice

Sketching
  • Types of Sketches
    • Single-view
    • Multi-view
    • Pictorials
single view sketching
Single-view Sketching
  • Technical purposes
  • Front view
    • Most descriptive features
multi view sketching
Multi-view Sketching
  • Technical sketch
    • Front view
    • Top view
    • Side view
multi view sketch

TOP VIEW

FRONT VIEW

R. SIDE VIEW

Multi-view Sketch
pictorial sketches
Pictorial Sketches
  • Quickly communicate an idea
  • Three dimensions in one view
    • Width
    • Height
    • Depth
pictorial sketches21
Pictorial Sketches
  • Three (3) types
    • Isometric
    • Oblique
    • Perspective
isometric sketch
Isometric Sketch

HEIGHT

WIDTH

DEPTH

isometric sketching
Isometric Sketching
  • Three equally spaced axes of 120°
isometric sketching24
Isometric Sketching
  • Receding lines
    • Typically 30° off horizontal
isometric sketching25
Isometric Sketching
  • Circular shapes appear as ellipses
isometric ellipses
Isometric Ellipses
  • Correct ellipse orientation
isometric sketching27
Isometric Sketching
  • Non-Isometric lines
    • Locate endpoints and connect
oblique sketch
Oblique Sketch

HEIGHT

DEPTH

WIDTH

oblique sketching
Oblique Sketching
  • Front view is drawn true shape and size
oblique sketching31
Oblique Sketching
  • Receding edges are usually drawn at an angle of 30°, 45°, or 60°
oblique sketching32
Oblique Sketching
  • Circles and curves drawn on frontal plane will appear true shape and size
perspective sketches
Perspective Sketches

1-Point Perspective

2-Point Perspective

perspective sketches35
Perspective Sketches
  • Objects appear as the eye would see them
  • Most realistic type of pictorial sketch
  • Most difficult pictorial sketch to draw
