1、First Year The first year design courses include Drawing, where the students learn to develop the 3- D visualisation and communication skills needed for engineering design; Product Design, where they receive an introduction to product evolution and the methods used in the first two phases of the des

AIMS The aim of this course is to enable students to: Understand the role of drawing and CAD in the design process. Make and interpret mechanic
5、al drawings. Solve simple geometric problems using graphical techniques. OBJECTIVES As specific objectives, at 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.
6、Make third angle projections of engineering objects, using the conventions of BS 308. Make isometric sketches. Make assembly drawings. Use a professional CAD package to create models of engineering components and assemblies. SYLLABUS Projection Theory Projection of points, lines and planes. Perpendi

The concept of the design, the accuracy and relevance of the calculations, and the test performance of the structure are also considered. A failure to meet the loading requirements in the test might thus result in only a slight reducti

Students failing to attend will be awarded no marks. (j) A number of prizes will be awarded for the best overall individual performances

The constraints, especially those associated with material properties, need to be known or specified, together with estimates for the likely level of aerodynamic performance. From these the
