I am trying to design a door hinge. I created a sketch in an assembly that defines the motion of the door through simple lines/pivots. I can move the components through their motion when in the sketch editor. However, the relations freeze when the sketch is exited (sketch is under-defined on purpose so door moves).
I was then planning on creating the parts (door, frame, hinges) that would be constrained to the sketch. Is there a way to keep the sketch from freezing when working at the assembly level?
