extrusion for attack/create devading

[medelettronica]

as from photo I seek help to create a spawning on a curved surface that allows me to insert a self-tapping screw to block 2 bodies together,
I created that hole from the inside with the extrusion function for the attack that created a small cylinder where the screw is screwed inside but I can't figure out how to bring the rigging back to the outside to not show the screw
Thank you.

use the "creation wizard holes" function both for the hole that will host the screw and for the rigged hole.
the main advantage lies in the fact that you can use it in 3d sketch environment.
