Feature Control Frames: Defining Feature Requirements

In the world of Geometric Dimensioning and Tolerancing (GD&T), precision is everything. The essential tool for specifying tolerances on part features is the Feature Control Frame. Whether you’re designing a critical aerospace component or a simple bracket, the feature control frame allows you to communicate how a feature should be measured and what its limits are in terms of form, orientation, location, and more. In this article, we’ll dive into what feature control frames are, why they’re vital for your engineering drawings, and how to apply them effectively.
