how to delete lines in catia v5r20

I'm having trouble with liney in catia drafting. In other words when I delete a line in catia drafting and for some reason UPDATE the drawing because of some modifications to the part, my lines that I HAVE DELETED pop up again.
Is there any way that deleted lines stay erased?

need to change to change your catia settings. Go to options>Mechanical design>drafting>view
here you have to tick the Keep graphical dress-up manually set on geometry.

Now you can hide or delete, after the update of your model also the hided or deleted lines wont come.

what does line mean? If they created when you take a view from solid, every update will generate them automaticaly. you must give specific example to which lines you delete? and you can hide some of them.
