As you see here, this is a three-piston engine model that I have modeled in Inventor. and animated in 3DS max. this is similar to the Machine Vise where a model was made in Autodesk Inventor, then brought into 3DS max for animation as well as rendering, then brought into Premiere Pro. Though this is much simpler to animate, but there were actually a few key differences that I did in this project then the machine vice.

What I did was animated the crankshaft for as a repeating 360 rotation and then link the connecting rods to the crankshaft for animation and then I use bone structure to make sure everything moves properly like the machine by being able to move up and down left and right, but the piston head only able to move up and down, not left and right.

Also, for this project, I didn’t just bring it into Max. I actually modified the engine to have a handle to spin because this is going to be 3-D printed in real life so that’s why the model is very different from the PDF that’s also why the engine block is much more taller and has feet four to stabilize it for that reason as well.
