This document contains a series of slides from a webinar presentation on geometric dimensioning and tolerancing (GD&T) given by Norakmal Bin Maamor from the Department of Human Resources Ministry of Human Resources. The presentation covers the fundamentals of GD&T including ISO 8015 and ISO 1101 standards, examples of applying position, concentricity, form, angularity and run-out tolerances to engineering drawings, and methods for measuring GD&T using tools like coordinate measuring machines, linear height gauges, and roundness machines. The goal is to educate attendees on the important role of GD&T in engineering design and quality control.
