- Freehand Sketching Freehand sketching is a method of making a drawing without the use of instruments. Most designers use sketches to think through an idea before making the final drawing. Freehand sketching requires only a pencil and plain or grid paper.
- Slide 3
- Freehand Sketching Cross-section paper may be used for freehand sketching.
- Slide 4
- Sketching Technique When sketching, hold the pencil with a grip firm enough to control the strokes. Your arm and hand should have a free and easy movement. As you sketch, rotate the pencil slightly between the strokes to retain the point longer. Initial lines should be sharp and light.
- Slide 5
- Sketching Technique Apply light pressure to avoid making grooves in the paper. Keep your eye on the point where the line will end; use a series of short strokes to reach that point. When all the lines are sketched, go back and darken the lines. Strive for neatness and good technique.

- Sketching Technique When sketching, grip your the pencil farther back than you normally would.
- Slide 7
- Sketching Horizontal Lines There are four basic steps.
- Slide 8
- Sketching Vertical Lines There are four basic steps.
- Slide 9
- Sketching Inclined Lines Locate the end points of the line. Position arm for trial movement. Sketch several short, light lines. Focus on end point. Darken the line.
- Slide 10
- Sketching an Angle First, sketch a right angle (90). Subdivide the right angle to get the angle you desire.
- Slide 11
- Sketching Circles and Arcs There are several methods of sketching circles and arcs: Centerline method. Enclosing square method. Hand-pivot method. Free-circle method. All are sufficiently accurate, so use the best method for a particular situation.
- Slide 12
- Centerline Method Locate centerlines. Mark off radius. Position arm. Sketch the circle in short sweeps. Darken the circle.
- Slide 13
- Enclosing Square Method Locate centerlines. Sketch a box equal to the diameter. Sketch arcs where the centerlines cross the box line. Sketch the circle.
- Slide 14
- Hand-Pivot Method First, position the pencil and small finger. Then, rotate the paper to sketch the circle.
- Slide 15
- Sketching Ellipses The rectangular method for sketching ellipses is similar to the enclosing square method for circles.
- Slide 16
- Proportion in Sketching Proportion is the size relationship of one part to another or to the whole object. Keep the same width, height, and depth in proportion. Unit method. Pencil-sight method.
- Slide 17
- Proportion in Sketching Gauge proportions using the pencil-sight method.
