Create associative point measurement (Menu > Analysis > Measure Point). In drafting use note and insert point measurement expression and create the leader by selecting the required point as terminating object.
Other way to use the PMI. Start the PMI application and use the 'Coordinate Note' command. I have created coordiante note for two points (center point and quadrent point of face) in Isometric view.
In drafting, create the same view (For which PMI Coordinate Note is created). In view settings under Common > PMI just select the option From Model View. You will have the associative x,y,z coordinates of point.
