If I create a component and place two instances and attach a dimension to each, then when moving an instance, the dimension moves with it. So Sketchup knows to which specific instance a dimension is attached. But, it seems to me that the API doesn’t reveal that information. The entity the dimension is attached to is part of ComponentDefinition and the position can be shared if the components tough/overlap.
Is there a way to find which specific instance a dimension is attached to?
