Detailed Outline
Introduction
- GD&T defined: Size, Form, Orientation, and Location (SFOL) — What we want and what we will take.
- Three boxes for GD&T: Feature Control Frames (FCFs), Datum Feature Identification (DFI) symbols, basic dimensions.
- Exercise: Control symbols, names, and feature control frame examples.
- Modifiers: Free State, Statistical Tolerance (ST), Continuous Feature (CF), and others
- Exercise debrief: Overview of everything
