I'm self taught on SolidWorks and so I don't know all the tricks and proper techniques. I am having a difficult time figuring out how to mate together two assemblies. I have a spring that I am wanting to mate into the bottom-center of a cylindrical cut into a block. I suspect the way I built my spring is complicating the mating process. I have attached a picture of the two items I am trying to mate.
Thanks for your help!
