I am trying to design the engine movement, but I can't find the relation between the connecting rod and the piston.
I think that the piston movement (y) should be controlled with an "sin x" function of the same angle that is controlling the drive shaft rotation, but how can I maintain the same length of the connecting rod?
The movement is not just a simple sine function.
Rather than trying to define the movement with an equation use a circle and intersect it with the line.
what kind of component did you use to create the curve? and the rotation?
I obtained the same result but rotating the evaluated point with rotate with axis.
anyway, thank you for your help.

OK it is just that when I saved the stills as jpg or bmp, paintshop pro does not seem to recognise the format. With png files it is OK. I don't suppose you have a version that can be loaded into 6.00059.
Yeah, I also have problems opening bmp files generated by grasshopper for some reason. Anyway png is a good format - smaller files than bmp, but still lossless unlike jpg.
I made the def in 0.7, and there is no way to save in an earlier format, but here is an image of it
