Aims

The aims of the course are to:

• Understand the role of drawing and CAD in the design process.
• Learn how to make and interpret mechanical drawings.
• Solve simple geometric problems using graphical techniques.

Objectives

As specific objectives, by the end of the course students should be able to:

• Understand projection theory and its use to make required views of lines and planes.
• Understand orthographic projections of solid objects.
• Make orthographic projections of engineering objects, using the conventions of BS 8888: 2008.
• Make isometric sketches and auxiliary projections
• Interpret existing orthographic drawings
• Use a professional CAD package to create models of engineering components and assemblies.
