The AS 1100 drawing reflects the correct scale, but we note exact measurements are required for the exam diagram.

Key Points for this Drawing:

  • There is very little actual sectioning in this drawing as it is being used to test if students know what to section. DO NOT section nuts, bolts or threads.
  • The small rectangle is the only part sectioned as it the only part cut that is not a nut, bolt or thread.
  • Although only 1 nut is shown the instructions say to draw both.
  • Use correct bolt dimensions for nut size.
  • Do not dimension unless asked.
  • Do not show hidden detail on sectioned side.
  • Sectioning lines should be on a 45 degree angle and 3 mm apart.

Notes on this drawing:

  • Do not dimension if not asked
  • Ensure section is offset, both larger holes and the smaller hole should be visible as the section is not one line, it cuts through all of them.
  • No hidden detail
  • Section lines correct width apart and angle (approx. 3mm and 45°)
