I want to create countersunk hole and then add threading on the hole. I think I can do this by creating two hole engine features- one for the countersunk hole and one for threading. I am trying to create hole for M3.5 tapped flat head screw. But, when I create the countersunk hole, the diameter of hole is larger than 3.5 mm and hence I am not able to add threading features. is there any way i can control diameter of hole.
