Lesson 1
Start by opening the Fusion 360 app.
In this lesson we will show how to make simple sketches and simple 3D operations.
The Sketch
In Fusion 360, everything is made of a sketch and then an operation on that sketch. To make a cube, you sketch out one face and extrude it, or add a height, to make it 3D.
We will start by sketching a simple square:
