Course Outline
Engineering drawing is a formal and precise way of communicating information about the shape, size, features and precision of physical objects. The drawings of the engineer are an obvious case of making visible the practical expression of the profession, the interpretation of which has a direct impact on the final product.
This 4-hr course provides a thorough explanation of how engineering drawings are structured and the conventions that are used in making them and reading them. The course is designed to demonstrate how to read mechanical and technical drawings of piping and mechanical devices, controllers, and instruments connected to the network of pipes in an industrial plant.
The course material is extract from Department of Energy, handbook (DOE-HDBK-1016/1-93), ENGINEERING SYMBOLOGY, PRINTS and DRAWINGS, Volume 1 of 2 and covers Module 1 and 2.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Intended
Audience
This course will be useful for anyone who interprets engineering drawings: product manufacturing, and quality engineers; inspectors; machinists; mechanical and process engineers, production personnel; fabrication and construction workers, purchasing agents; etc.
Benefit to Attendees
Attendee of this course will get to learn the basic symbology, common standards and conventions of the engineering drawings. The knowledge gained will be immensely useful in preparation, interpretation and reviewing of P&IDs, logic diagrams, fabrication, construction, architectural and other forms of engineering drawings.
Course Introduction
The ability to read and understand information contained on drawings is essential to perform most engineering-related jobs. Engineering drawings are the industry's means of communicating detailed and accurate information on how to fabricate, assemble, troubleshoot, repair, and operate a piece of equipment or a system. To understand how to "read" a drawing it is necessary to be familiar with the standard conventions, rules, and basic symbols used on the various types of drawings.

Course Summary
Drawing is the universal language of engineering. Drawings from an engineer provide a raw account of the fundamentals that will eventually go into making something useful and necessary, something which may save time, effort, record, or make a thing work. The five common categories of drawings are:
- P&IDs
- Electrical single lines and schematics
- Electronic diagrams and schematics
- Logic diagrams and prints
- Fabrication, construction, and architectural drawings
Working with any of these engineering drawings type involves analyzing, making decisions, and processing data. This course provided a good understanding of drawing terminology and knowledge of the view representation, dimensions, tolerances, and other miscellaneous items used on the mechanical devices and piping. Representation of instruments and controllers on P&IDs and piping layout drawings of an industrial plant are also provided.
Quiz
