How to grab and move in world coordinates?

I would like to move the points of my mesh and set them in specific places, like (-1,-0.33,0). How do I do that?

I can grab the vertice and then move them around even define accurately where the value of the transform, by doing grab move along axis, but when I use the global move the transform is acording to the center of the object, and local move is acording to the center of the object to but uses the axis of the object instead of the world axis.

I am making some objects that need accurate mesures as they are supposed to fit together.

use the N-Tranform Key
there yoou can set the location ect… of each vertex
