Differentiating between "Features" and "Features of Size is both one of the most confusing and one of the most important topics in GD&T. Mastering it early in the course will help you to better understand the different ways that controls can be applied as we go through this course. For this post: 1. Pick a common household object 2. Identify at least 4 elements (either features or features of size) on the object 3. Categorize the element as either a feature or a feature of size 4. Explain why you have categorized the element in this way. As a stretch goal, consider further classifying a feature of size as being either regular or irregular.
