Orthogonal Projection and Technical Drawing Fundamentals

Understanding how to represent three-dimensional objects in two-dimensional space is an essential foundational skill for engineering and technical design. This course provides a practical introduction to orthogonal projection and graphical modeling principles. You will start by building a strong vocabulary of geometric terminology, coordinate systems, and projection rules. As you progress through written lessons and structured exercises, you will learn how to break down complex 3D objects into precise orthographic views and interpret technical drawings with confidence. What you'll learn: - Understand foundational concepts of orthogonal projection, view placement, and coordinate planes - Construct accurate front, top, and side views for diverse three-dimensional shapes - Apply standard line styles, dimensioning rules, and sectioning principles - Interpret technical projections to visualize spatial object relationships correctly - Analyze geometric intersections and true lengths using descriptive geometry principles - Understand how traditional projection methods connect to modern digital CAD drafting standards The course begins with fundamental definitions and theoretical principles of projection before moving step-by-step through view construction, dimensioning, and CAD integration concepts. This course is tailored for complete beginners, students, and practical learners with no background in engineering graphics or descriptive geometry.
