Ok refound again the Vclone use ! :)
You must play with axis gizmo for the good one orientation and placement result!
Here i am on the external surface of the cylinder (for better see the axes )
you must take of course the internal axis depending of the result whished!
Good luck! :)
Ps you have a possibility of History inside the plugin itself if wanted!
Enable or disable Scale / Vectors and some variations also!
A very versatile cool one!
