Use GD&T to specify the functional requirements of parts
- [Instructor] Geometric Dimensioning and Tolerancing is an enormously powerful tool that allows engineers to define the physical relationships between features more specifically than is possible with simple linear dimensions and tolerances. In this video, we'll introduce you to the concept of geometric dimensioning and tolerancing, show you how it might be applied to an example part and discuss the challenges of using GD&T when it comes time for manufacturing. GD&T is a framework for controlling the form, location and orientation of features with a very high level of specificity. A special symbolic language is used to succinctly and consistently communicate these requirements on drawings. In some cases, GD&T allows engineers to control characteristics that cannot otherwise be specified with simple linear tolerances. However, the real value of GD&T is that when used properly, it allows for the absolute maximum tolerance…
