How do you make a DynamicAnnotation? For example, if there is 2 receptacles that are stacked on each other an elevation view. When you are placing the receptacle on the wall, how can you make it so that it doesn't just duplicate the annotation on the same place on the floor plan? Additionally, how do you make it so that if the receptacles that are places near each other that the annotation is spaced away from each other? Also with scaling, how can this work seamlessly without stacking or overlapping on each other?
