Move all the vertices

Hi, I created a parallelepiped with nomad and then switched to side view and locked the view.

I want to use the tools to modify the vertices of the parallelepiped in order to give it the shape that I want to all parallelepiped. Unfortunately, I can move only the vertices of this view and not those that are behind the same vertices ( that you see when I Watch in front view). Moreover the vertices I can move, go in other directions (toward the front view), instead I want move then only down, up, right and left.

Could you help me understand what I’m doing wrong?

Thank you.

I hope i got you right you mean an infinite depth move like in zbrush?

Make sure you disable „frontfacing vertex only" and if i remember the setting right

Idk about the vertices moving in different directions but uh did you have an offcenter symmetry maybe? World instead of local? Or accidentally got normal-function activated?
