Visible lines represents_______________

• Visible lines represent axes of symmetry and are important for

  interpreting cylindrical shapes

• Visible lines represent edges and boundaries that cannot be seen

• Visible lines are used to indicate imaginary features. For

  example, they are used to indicate the alternate positions of moving parts, and

  adjacent positions of related parts.

• Visible lines represent visible edges and boundaries.
