I'm having difficulties using the chain component tool in SolidWorks. I can create the chain but when I mate the ends to the parts that are moved by the chain, SolidWorks does not cooperate. Perhaps I am doing something wrong. The chain has 151 links in total but for testing purposes I have it set as 30. As of right now, Only one end of the chain is mated. When I try to pull on the chain, SolidWorks says that the selected component is fully defined and cannot be moved. I'm not sure why this is because the part that the chain is mated to can move freely back and forth when it was not connected to the chain. I've attached the zip file containing the files. Any help would be appreciated.
