I have created a sketched path on a part that I use to make a path mate between two parts. I can make the bolt travel along the path. But one part are a cylinder that has been made flexible and the other part is an assembly that should move up and down accordingly. 

But I can`t seem to get it to work, path travel is fine, but at the same time I need to be able to see that the cylinder and bench moves too. What am I doing wrong?
