Engineering Drawing | Amir Putra Md Saad, Ir. Dr.

Synopsis

This subject introduces student to the use of technical drawing in an effective way for communicating and integrating with engineering concepts. Such environment will provide a platform where the engineer can share and exchange information. This subject will also enlighten the student on the significant changes in the engineering and technical graphic due to the use of computer and CAD (Computer Aided Design) software. At the end of the course, student should be able to apply the skill and knowledge of engineering drawing to interpret design, using graphics method such as geometric drawing, orthographic projection, isometric, machine drawing, detailed drawing, and basic CAD software.

Course Learning Outcomes

By the end of the course, students should be able to :

1.	Identify and define the basic requirements of engineering drawing according to standard
2.	Translate objects into geometry and orthographic drawings
3.	Construct assembly and detail drawing, and solid modeling
4.	Translate objects into sectional and isometric drawings

Teaching Methodology

Lecture will given to expose the student on the principle of engineering drawing
Students are required to attend studio to have an hand-on practice on engineering drawing
Students are required to produce a complete production on selected product for the project
