  1. Apex The highest vertex of a solid

  2. Plane An flat surface of no thickness with infinite length and width

  3. Generator A line that generates a surface

  4. Locus The path of a point under certain conditions

  5. Dihedral Angle The true angle between two surfaces or planes

  6. Orthographic Projection An internationally recognised method of represent 3D objects using 2D drawings

  7. Horizontal Trace A line representing where a plane meets the horizontal plane

  8. Skew Lines Lines which are not parallel and do not intersect even if extended

  9. Vertical Trace A line representing where a plane meets the vertical plane

  10. True Shape A view of a shape when viewed perpendicular to the shape

  11. XY Line Where the horizontal plane and the vertical plane cross

  12. Elevation The view projected onto the Vertical Plane

  13. Plan The view projected onto the Horizontal Plane

  14. End Elevation The view projected onto the End Vertical Plane

  15. Rebatment The rotation of a plane or surface until it is coincident with another surface

  16. Arc Any part of the circumference of a circle

  17. Area The size of a surface measured by the amount of square metres it covers

  18. Development Unfolding a 3D object onto a plane

  19. Major Axis The longest axis through the centre of an ellipse

  20. Minor Axis The shortest axis through the centre of an ellipse

  21. Tangent A straight line that touches a curve at one point only (Point Of Contact)
