I am using step to send parts for making, I try to eleminate the need for making 2D cad, it will be great if we can have a kind of counterbore input pre-hole, of a value, ex.: 0.5mm depth and if the thread ends that finish with the drilling hole diameter of ex. 0.5mm
This way, it will be easy to anybody that see the 3D modeled threaded hole to see the drilling diameter and the Thread centered diameter 9ex. an M4 will have a 0.5mm final hole that is 4mm dia), so instead of trying to find the center of the 3D thread (it's look off axis), the last 0.5mm depth will be 4mm x 0.5mm deep.
