This tutorial teaches you how and why to fully-define your sketches in Fusion 360. This is a foundational concept that all beginners must learn if you want to create proper parametric models.
Fully defining a sketch is done through the use of constraints and sketch dimensions. In this tutorial, I break the concepts down with a simple part example. You'll also learn some tricks and tips to figure out why your sketches aren't yet fully defined, including how to achieve the lock icon.
