Fusion 360 Design Best Practices Question (Am I on the right track?)
Ok, let's go down the main two ways to a part, and in practice you usually use both to design for 3D printing. Only for machining, you try to keep to the cutting method only.

Cutting Method
Building Method

You start with a piece of &quot;stock&quot;. A cube or cylinder created by extruding the simple shape. Now you go and create profiles that you either extrude into the part or rotate around the axis - your profile &quot;cuts&quot; the &quot;stock&quot;.
