Engineering Principles for Technicians: A Practical Workbook Using AutoCAD. Learning Technical Drawing from the Ground Up (AutoCAD and Technical Drawing for Engineering Technicians 1)

PrefaceEngineering drawings are the language of manufacturing, construction, and technical work. Technicians use this language every day, to build parts, inspect components, communicate with machinists, and prevent costly mistakes on the shop floor. Yet many beginners are overwhelmed by traditional engineering graphics textbooks that focus heavily on theory before showing how drawings are actually created and used.This workbook was written to close that gap.This book is designed specifically for technicians who are just starting in engineering graphics and computer-aided drafting. Complex engineering ideas are introduced in simple, practical terms, with a strong emphasis on how drawings are created, read, and used in real technical environments. You do not need to be an engineer to succeed here, but you do need clarity, practice, and good habits. That is what this workbook provides.The reference material for this workbook is Engineering Graphics Essentials (EGE). However, this is not a theory-heavy rewrite of that book. Instead, EGE is used as a conceptual guide, while this workbook focuses on hands-on learning using AutoCAD. Every topic is paired with drawing practice so that ideas immediately turn into skills.To support this goal, the workbook includes 12 structured AutoCAD lab walkthroughs. These labs are written step-by-step and assume no prior CAD experience. Each lab is designed to build confidence with the software while reinforcing core engineering graphics concepts such as:Orthographic viewsDimensioning and scalingLine types and line weightsSection viewsBasic tolerancing conceptsClear and readable technical communicationThe AutoCAD labs are not just software tutorials. They are technical drafting exercises, designed to mirror the types of drawings technicians encounter in manufacturing, quality, and inspection settings. By the end of the labs, students should be comfortable creating clean, standard-compliant drawings and understanding why those standards matter.This workbook is intended for use in Engineering Technology Graphics courses, such as MET 101, and is best used alongside hands-on instruction and discussion. Students are encouraged to sketch by hand, think visually, and ask questions, because good drafting is not about clicking buttons, but about understanding how parts are made and inspected.If you approach this workbook with patience and curiosity, you will build a skill set that follows you well beyond the classroom. Technical drawings are not just assignments, they are tools. Learn to use them well. Read more
