Thank you.

You're right
precise better the problem
I should create hooks on the inner face of a cracked cylinder and emptied as you see in the picture I would like to make the hook base coincide with the inner face
I tried converting entities on my face but it answers me with error!
Of course I repeat that you do not speak with an expert but a passionate! :tongue:

set the display " visible hidden lines" trace the sketch using the hillside with the inner edge of your cylinder.
