Engineering Drawing

COURSE DESCRIPTION

This course deals with the practices and techniques of graphical communication application of drafting instruments, lettering scale and units of measure; descriptive geometry, orthographic projections, auxiliary views, dimensioning sectional views, pictorial drawing requirements of engineering working drawings and assembly and exploded detailed drawings.

COURSE JUSTIFICATION/RATIONALE

This unit will enable students to acquire and use engineering drawing skills as a means of accuracy, clearly communicating ideas, information and instructions.

LEARNING OBJECTIVES

By the end of this course, the student should be able to:

§  Draw the title block

§  Describe geometric projections and views in drawing

§  Outline different line types.

§  Apply different drawing skills in engineering fields.

LEARNING OUTCOMES

A student on completing this course is expected to:

§  Locate Title Block, revision level, and scale information and explain the importance of each.

§  Distinguish an isometric projection from an orthographic projection and explain the differences of each.

§  Apply principles (rationale and application) of orthographic projection (i.e., most common views used, most important view, orientation of the three views, etc.).

§  Identify the missing third view from a choice of four possible responses.

§  Identify and explain common line types used on prints.

§  Identify drafting symbols and selected features associated with metal forming (i.e., shearforms, bends, extrusions, notches, holes, thread callouts, etc.).

§  Select 12 basic GD&T symbols and provide a working definition of each.
