Apply geometric construction principles.

Application should include

  • bisecting lines, arcs, and angles
  • dividing lines into equal parts
  • constructing parallel and perpendicular lines
  • constructing angles and triangles
  • constructing tangent lines and arcs
  • constructing polygons
  • constructing ellipses.

Process/Skill Questions:

  • How are tangent lines and arcs used in drafting?
  • What are some examples of basic geometric shapes used in drafting? In what situations might these shapes be used?
  • Why is knowledge of basic geometric construction principles valuable to a drafter?
  • How do the geometric construction principles transfer to the CAD environment?
