Hi there !

Sorry, I'm new to Blender I have a question that is probably stupid, but is there a way to grab specifics vertex, or edges that are all scatered on a cylinder surface, toward the center axis of it, all of them at once ?

To explain, after some basic tutorials I'm trying to design a complex object on my own. I settled for Han Solo's DL-44 because it's all geometric and full of details at the same time =p

Modeling the barrel, I'm trying to make regular creases around the muzzle part :

So I've split the faces on my modeled part so that "pushing down" some vertex would achieve something close :

How it should look after

So, I can do this one crease by one, like the picture above, but apart from it being tedious, it makes for irregularities and differences between each crease as I'm eyeballing it. Top crease is easy because on the global Z axis, but any adjacent one is a nightmare to push down toward the cylinder axis properly.

What I wanted was to select all comparable vertex and squish thew down toward the center axis of my cylinder at once, to get a neat and regular pattern. But once grabbed, I can't find a way to bring them inward :

Do you know what tool and parameters I should use ?

By te way, should you have a better way in mind to make those crease, please share it !

Thank you for any help !
