Changes from Previous Offering

In conjunction with MECH303, this unit has been altered drastically to provide students with more hands on experience in using CAD and using automated manufacturing techniques. It is anticipated that enhancing these skills will increase the benefit that students will obtain in future offerings of ENGG200/300. As a result, the content of this unit is different and previous year assessment tasks are not representative of what should be anticipated this year.
