measuring a countersink

Good evening Pcdmis masters, I`m fairly new to Pcdmis, and i would love to get some help , I am trying to measure a Countersink Dia at the intersection of the top surface on this part, the available area is very limited and the thread leads are not clocked to the model to get an auto cone reading accurately, is there any method i can use to first identify the rotation of the the double lead thread and then construct a cone avoiding the thread lead`s in order to get an accurate reading? any tips will be appreciated ,thanks in advance
