Engineering Drawings - Mechanical

COURSE NO: M04-015
Engineering Drawings - Mechanical
Course Highlights

This online engineering PDH course begins with 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.


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. 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 PDH online course is intended for mechanical engineers, design professionals, product manufacturers, inspectors, machinists, production personnel and construction workers who are involved in the interpretation of mechanical engineering drawings.
