I am looking do drive 4 seperate assemblies, that are in an upper level assembly. Think of these 4 assemblies like tires on a car and think of the upper level assembly as the car. I need to drive these tires to different wheel bases (both length and width). There are many ways to drive these assemblies but I am looking to do drive them with a sketch in the upper level (car level) assembly. I want to do this for ease of use for the other people in my group who aren't as SolidWorks savy. The I have this idea in action but am having major "Overdefining" and "remodel" errors. Does anyone have any ideas to help me clean this problem up?
