Maybe this is what you are looking for???
Since it is not allowed to constrain the dependent node on a weighted link, use a rigid spring to transfer the "manipulation". Then the SPC on the other end of the spring can be manipulated by a function.
There is a restriction on the magnitude of rotations with Creo "mulitpoint constraint" in large deformation analysis. Animations usually my best way to detect when things start acting wrong/strange.
This spring-link method is a common method. You will find many similar and probably better examples from @skunks if you search. Posting a specific example similar or simplified from what you want to accomplish would help us help you.
