Most Engineers Misuse Position Tolerance — Here’s Why

Position tolerance is one of the most powerful—and most misunderstood—controls in GD&T and technical drawings. If hole locations, patterns, or assemblies fail to line up, position tolerance is usually the reason. In this video, you’ll learn: What position tolerance really controls (and what it doesn’t) How the tolerance zone actually works in real parts How datums affect location and functional assembly Common mistakes engineers make with position tolerance Practical drawing examples you can apply immediately This explanation applies to both ISO GPS and ASME Y14.5, making it essential knowledge for design, manufacturing, and quality engineers.
