Computer Aided Draughting


This course is an introduction to Computer Aided Draughting using Autodesk's AutoCAD software. You will learn how to design any object in CAD (Computer Aided Design). From a simple object, like a circle, to a wine glass, hair-dryer, house plans, etc. There have been several versions of Autocad, and it is a good idea to sign up at Autodesk Students, where you will be able to obtain the software for free. The lecturer is involved in this process.

Accurate, scale drawings can be created. 2D and 3D models can also be created. It gives the designer full control over the design from start to finish. The computerised model can be viewed and rendered in various ways. This is truly a powerful application.

The CAD161S exam

Past exam papers

The exam in Oct/Nov 2008

The paper consisted mostly of shortish questions. A model was given, with some of the commands, and one had to fill in the missing commands. We also had to write down how one would do certain things in Autocad, e.g. if you need to draw a square.

How to pass CAD161S

Study tips

Play around in Autocad, Practise. Memorise the commands and steps.

E.g. To chamfer a solid object:

  1. Type CHAMFER at the command line or from the Menu select Modify | Chamfer
  2. Select the edge of the base surface
  3. Specify the base surface distance
    • To select a different base, enter "n" or press <Enter> to use current surface
  4. Specify the adjacent surface distance
  5. Specify the edges to chamfer
  • This is a hands-on course. Practise. There are a lot of commands you need to remember for the exam. You must be able to write step by step how you will create your drawings, objects, views, etc. The list of commands is almost endless.
