Geometric Dimensioning & Tolerancing – The mysteriously complex language used to communicate your engineering intent to the world.
Enhance your engineering career by understanding how Geometric Dimensioning & Tolerancing, an international design language is used to communicate your ideas effectively to the engineering community through a 2D drawing or 3D model to meet your functional requirements.
What you can learn.
- Understand the history of Geometric Dimensioning & Tolerancing (GD&T)
- Identify the significant differences from traditionally dimensioned engineering drawings
- Evaluate how the main 14 geometric symbols are used in defining the functional requirements of a part
- Understand the basics of Rule 1, the “envelope principle” and how it is the pillar of GD&T
- Learn how to simulate datums, where they come from, and how to use them to establish the Cartesian coordinate system to locate features in 3D space
About this course:All aspects of the manufacturing industry requires communication between multiple engineering disciplines ranging from design, manufacturing, inspection, down to quality control whether in the aircraft, automobile or even the consumer electronic industry. To communicate the design intent between disciplines, a complex international engineering language defined as Geometric Dimensioning and Tolerancing is used on 2D drawings or 3D models. This language is not widely taught in educational institutions, however the knowledge of GD&T is transferred mainly through coworkers or peer to peer training. In doing so, many learn and interpret it incorrectly which result in repercussions such as parts and assemblies being manufactured incorrectly, late deliveries due to rework and rejections, and ultimately leading to financial loss. In this course, you will learn the importance of GD&T and what separates it from traditionally dimensioned drawings used for the past several hundred years, and why it is critical in today’s time of mass production. Also you will learn how the 14 geometric symbols define the part’s geometry and the application of it to meet its design requirements.
