FreeCAD: kinematics Skeleton and Animation via a Master Sketch and Python Tutorial

In depth tutorial explaining the steps to create a basic piston animation using a master sketch containing constraints as the rigging for a Kinematic skeleton that we can uses as bones for our bodies in FreeCAD.

This technique covers creating clones of your sketch with constraints that are linked to the master sketch which acts as the bones for the movement of the mechanism. Any changes to the master sketch are reflected automatically to the clones.

I also introduce you to using python macros to drive the piston animation by moving constraints via the script. We cover working with macros, programming in python code, using the sketch workbench, creating constraints, using construction constraints, the importance of changing visibility of elements and the issues if we don't, using the part design workbench and generally interpreting and planing the movement of the mechanics and converting these to a CAD solution.
