Engineering Sketching for Design and Communication

John Andrew, P.E.

Course Outline

Freehand sketches are vital to the innovation process. Simple forms sketched on paper can represent the most complex products and manufacturing systems.

This 2-PDH course presents freehand sketching as a method for

Major topics of this course are:

  1. Freehand Sketching
  2. Typical Project
  3. Process Plant Design
  4. Equipment Performance Graph
  5. Manufacturing and Process Plant Layout
  6. Sketching Techniques

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

This course presents freehand sketching for:

Intended Audience

The information will be especially useful to students, entrepreneurs, engineers, and innovators who want to review some important applications of sketching in an engineering environment.

Benefit to Attendees

Attendee of this course will be able to communicate appropriate and cost saving industrial products and manufacturing systems with freehand sketches in a timely manner.

Course Introduction

Mechanical, electrical, piping, structural, chemical, instrumentation, environmental, industrial, and process engineering disciplines use graphics in one or more forms. The freehand sketching techniques described in this lesson apply to all engineering disciplines.

Course Summary

Unfortunately most universities do not a lot much time to engineering graphics. This subject is left to the private and public technical colleges. This short and to the point course attempts to partially fill the education gap by showing basic engineering sketching methods. Sketching is a simple way to speed up the communication of new engineering concepts.
