© IIGDT – GD&T Introduction & Fundamental Principles - May 28, 2006 This method of tolerancing allows the axis of the hole to move plus something and minus something in the X and Y direction. 50 0.1 4X Plus / Minus Tolerancing 0.1 This creates a square tolerance zone in which the holes must lie?
© IIGDT – GD&T Introduction & Fundamental Principles - May 28, 2006 Linear Transformation to GD&T Geometric Dimensioning & Tolerancing (GD&T) creates cylindrical tolerance zones by removing the tolerance from the dimensions and applying it to the features. In this example, the geometric control is position. Dimensions are basic boxed, theoretically exact, with no tolerance Position Symbol Total Tolerance Diameter Symbol 4X
