Drawing Tools

Orthographic Drawing

• A two dimensional drawing of an object that is
  viewed from one side
• Hidden lines (dashed) are drawn to show areas of
  an object that are not visible from the view
  taken of the object.

Orthographic Projection

• A flattened drawing of an object with three sides
  drawn.
• Front, Top and Right Side
• Each drawing must be aligned properly.
• Projection lines are drawn out from each side of
  the object to assist with the drawing of the next
  view.

Isometric Projection

• Object is drawn on a 300 angle
• The three views from orthographic projects are
  used in the isometric drawing.
• Hidden lines are used to show parts of the object
  that cannot be seen from the chosen viewpoint.

One Point Perspective

• The face of the object is in front of the viewer
  and all orthogonal lines recede to one vanishing
  point.
• The back of the object is drawn with parallel
  lines to the front.
• As objects move closer to the vanishing point
  they appear smaller.

Two Point Perspective

• The corner of the object faces the viewer and is
  drawn with a vertical line.
• Orthogonal lines are drawn to two vanishing
  points and the edges of the object are created
  with vertical lines.
• As objects get closer to the horizon line they
  appear to become smaller.

15
Three Point Perspective

• Similar to two point perspective except that
  vertical lines are drawn to a third vanishing
  point.
• Third vanishing point is determined by the
  baseline and point of sight.
• The illusion of depth is enhanced by the third
  vanishing point.

Drawing Techniques

• Hatching-parallel lines
• Cross-hatching-parallel lines that cross over
  each other
• Stippling-small dots
• Gradient-shading
• Value Scale-Gradual transitions from light to
  dark.
