Engineering Drawing: Projection of Planes for CAD Workflows

Understanding how three-dimensional objects are represented on flat surfaces is a fundamental skill for every engineer and designer. This course guides you through the core principles of the projection of planes, bridging the gap between classical engineering graphics and modern computer-aided design systems. By working through clear written explanations and structured spatial exercises, you will develop a strong visual intuition. You will learn to analyze, orient, and project various plane surfaces, equipping you with the essential drafting logic required for precise CAD modeling. What you'll learn: Understand the fundamental terminology of engineering projections and quadrant systems; Analyze the behavior of perpendicular, parallel, and inclined planes relative to reference views; Determine the true shape and size of oblique planes using auxiliary projection methods; Apply projection principles to locate traces of planes in multi-view orthographic drawings; Connect classical projection rules to modern parametric CAD sketching and reference plane setup. The course starts with essential terminology and the mechanics of orthographic projection before moving into step-by-step methods for locating and orienting diverse plane surfaces. You will conclude by exploring how these manual drafting concepts directly translate into modern 3D modeling coordinate systems. This course is designed for beginners, engineering students, and aspiring CAD drafters, with no prior drafting experience or specific software required.
