how can I move a vertex towards the origin? Good evening,
Can anyone explain me how to move the selected point towards zero through that axis?
(That point is not the object center point)
Thank you very much.
Snap your cursor to the desired location with Shift+S. 

Set your Pivot Point to be the 3D Cursor

After that, select your first vertex and press S to scale it toward the 3D Cursor. 

Scaling to zero will put the vertex directly on your 3d Cursor.
