I want to get sketch line information using dimension property. I was successful getting all sketch dimension values as well as sketch line information(start point, end point) separately using their own properties but I want to get a link between these two information for example if I have a dimension information, i should be able to get sketch information on which this dimension has been created. More details is shown in figure:

Is there any way doing this. I was not able to get any concrete information from API as well.
