An engineering component is required to have the following features:

30 mm spotface
10 mm counterbore, 8 deep
6 mm through.

Which of the following shows the correct dimensioning?

Show Answers Only

`A`

Show Worked Solution

The vertical arrow represents how deep the counterbore should be, which is 8mm (given in question), therefore the answer is A or C.
However C does not have the correct symbol for counterbore, instead just stating 2 diameters next to each other.

Specifications for a Ø10 steel bar require it to have a tolerance of `pm`0.05 mm.

What is the permitted range of diameters for this bar?

9.90`-`10.00 mm
9.95`-`10.00 mm
9.95`-`10.05 mm
10.00`-`10.05 mm

`C`

Show Worked Solution

Upper limit = 10.00 + 0.05 = 10.05 mm
Lower limit = 10.00 – 0.05 = 9.95 mm

Benefits of using AS 1100 standards

Communication between manufacturers and designers is of higher quality, more accurate and involves fewer ambiguities.
AS 1100 is based on international standards so drawings can be easily shared between countries.
One project can be assigned multiple designers.
Cost effective as interpretation errors are minimised.

A general purpose bolt drawn to AS 1100 drawing standards is shown.

What is the diameter of the bolt?

8.75 mm
10.00 mm
14.00 mm
18.00 mm

Show Answers Only

`B`

Show Worked Solution

The width of the head of a bolt is 0.7 × the diameter, therefore the diameter is 10 mm.

Which engineering drawing shows a bracket correctly dimensioned to AS 1100 drawing standards?

Show Answers Only

`D`

Show Worked Solution

By elimination:

Arrowheads are used for measurements instead of crosses (eliminate `A` and `C`).
In `B` the radius symbol points to the arrow marking diameter (eliminate `B`).
