Geometric Dimensioning & Tolerancing (GD&T)

Reading and interpreting ASME Y14.5 feature control frames on engineering drawings: form controls (flatness, straightness, circularity, cylindricity), orientation (parallelism, perpendicularity, angularity), location (position, concentricity, symmetry), runout, and profile, along with material condition modifiers (MMC, LMC, RFS). Essential for quality inspection, CMM programming, and anyone who needs to build or accept parts to a real tolerance instead of a plus-or-minus note.
