MTT 131 - Engineering Graphics I & Blueprint Reading

3 Credit Hours

As an introduction to mechanical drafting and sketching, this course is designed to provide the machinist apprentice and others working in the industry with a basic understanding of the “language of industry” called graphics. The student will learn and apply the fundamental principles of mechanical drafting and sketching to graphically describe machine parts. A major goal of the course is to provide the student with the knowledge to be able to completely and accurately describe machine parts by making and using working drawings. Individual instruction is provided along with lecture presentations and hand out materials. The basic principles of reading and interpretation of industrial drawings will be presented. Emphasis is placed on the skills that are needed to understand the drawings and relate them to the machine trades. The course will include these major topics: lines and symbols; orthographic projection; one, two, and three view drawings; auxiliary views; dimensions and tolerances; sectioning and thread representation.
