I have a simple assembly that has about 15 components. One of which is a sub assembly that is a Linear Rail. In the rail assembly there is a limit mate to define the travel of the truck. However in the top level assembly those limits limits are working correctly. The sub assembly is made flexible in the top assembly but when you move the movable component its limit are off? Is this a bug or is there something I need to do to have the mates of a sub assembly translate correctly when added to a larger assembly?

Thanks
