This section is to help students who wish to present their drawings to the Workshop Technicians for manufacture.
Before issuing your project drawings to the engineering workshops please take a few minutes to scan through these guide notes, it will save you and the technician time.
The purpose of your engineering drawing is to communicate information to the technician.
Basic required information on a detail part drawing includes:
Name of part
Dimensions, including overall sizes.

Here are some examples of part drawings
Line types are also used to convey information.
A continuous line is for outlines.
A dot dash line indicates the centre of a part. _ ___ _ ____ _ ______ _

Drawings should always be in Third Angle Projection
An example of Third Angle Projection
Be aware that drawings are always read as Third Angle Projection unless stated otherwise.
3D rendered, wire frame, or solid model drawings are always useful as additional visual information but unless they are fully dimensioned and carry all the material, quantity, and assembly information they should not be presented as working drawings on their own.
