This class will touch on the engineering/design practice of tolerancing parts/drawings using Geometric Dimensioning & Tolerancing (GD&T). The practice has been used in the manufacturing industry for generations, but people tend to shy away from it due to the confusion and rumors that surround it. This class will discuss what GD&T really is and how it can greatly help in making your designs more accurate-and, in turn, save on production waste by way of rejection of far fewer parts that are actually within tolerance.

Key Learnings

  • Understand how to use GD&T
  • Understand how GD&T will validate your design prior to building a prototype
  • Understand how GD&T will help reduce manufacturing waste in regards to rejected parts
  • Understand the basic concepts of GD&T
