For 3D printing, CNC milling or for the manual assembly of complicated constructs one needs a formal specification of the workpiece, i.e., its parts and how these come together. The process to get there is called Computer-Aided Design (CAD). The process to transform a CAD model into a series of instructions that can be performed on a machine is called Computer-Aided Manufacturing (CAM). FreeCAD can do both, the prior yet a bit better than the latter.
