If you are new to the mechanical construction or maintenance industry and have wondered what all the different shapes and symbols on a mechanical drawing mean, this course is for you. Instructor Christopher Randall explains how to read the drawings and schematics for heating, venting, and air conditioning systems as well as plumbing and piping plans. Learn the difference between process flow diagrams (PFDs) and piping and instrument drawings (P&IDs), how to read and name components of both a simple and a complex P&IDs, and how to read the specific symbols and marks on hydraulic diagrams. Join Christopher in this course to gain a solid understanding of the purpose of each of these drawings and, even better, how they work together.
