On successful completion of this course, students will be able to use the engineering drawing manual tools in addition to the free hand sketching, draw all views and the isometric view, extract the missed views and sections, and have a brief idea on using the engineering drawing software.

The course provides the undergraduate engineering student with a background in descriptive geometry, orthographic projection, engineering drawing standards and annotation, and computer-aided engineering graphics. Point line and plane relationships in projection; multi-view engineering drawings; auxiliary and section views; basic dimensioning and annotation.
