This is not an in depth tutorial of how to use Fusion 360, rather an overview of some of. Through his totally-addictive blog posts and videos on his YouTube channel, he shares his experience so people can create and make their product in greater happiness. In this very first episode, I introduce you to some of the basics of the CAD software Fusion 360 and how I used it to go from a blank sheet, so to speak, to a fully framed RC airplane model based on the classic and ground breaking L-1011 Airliner.

Make sure you fully define your sketch (From blue to black). If not, someone can easily change the geometry by dragging a corner. It is very important that you get in the habit of fully constraining your 2D sketches, before extruding them into 3D. If you have a hard time figuring out what constraint or dimension you need to apply, you can try to drag a corner with your mouse. Fusion 360 indicates this by turning sketch geometry from blue to black. This means that the sketch is completely fixed. When you are applying your constraints and dimensions, your final goal is to fully define the sketch. For this example, we will apply horizontals and perpendicular constraints. Constraints are like rules for the sketches. It is a good rule to start adding constraints before dimensions. You will use constraints and dimensions to tie everything down afterward. When you start your sketch, just create something close enough to your finished geometry. Since we don’t have any solids on the screen, when starting with an empty canvas, we will be picking a plane for our first sketch. Remember, you can only sketch on a face or a plane. 
It’s worthwhile to turn on the origin, as it is important we connect our first sketch entity to it. In this example, we are going to sketch up a basic shape, while following a few sketch rules. In the video above we look at the Sketch Basics of constraints and dimensions for Fusion 360.
