Unity convert objects vertice vector3 to world position

After research i found that transform.TransformPoint(Vector3) method is used to convert Vector to world space. But for me that method do not change. I have Box class:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Box: MonoBehaviour
{
    public string named;
    public string id;
    public Vector3 dimensions;


    public Vector3 boxLeftBottomFront;
    public Vector3 boxRightBottomFront;
    public Vector3 boxLeftTopFront;
    public Vector3 boxRightTopFront;
    public Vector3 boxLeftBottomBack;
    public Vector3 boxRightBottomBack;
    public Vector3 boxLeftTopBack;
    public Vector3 boxRightTopBack;

    private void Start()
    {
        this.GetComponent<MeshFilter>().mesh.recalculateMeshByBounds(dimensions);

        boxLeftBottomFront = this.GetComponent<MeshFilter>().mesh.vertices[3];
        boxRightBottomFront = this.GetComponent<MeshFilter>().mesh.vertices[2];
        boxLeftTopFront = this.GetComponent<MeshFilter>().mesh.vertices[4];
        boxRightTopFront = this.GetComponent<MeshFilter>().mesh.vertices[12];
        boxLeftBottomBack = this.GetComponent<MeshFilter>().mesh.vertices[0];
        boxRightBottomBack = this.GetComponent<MeshFilter>().mesh.vertices[1];
        boxLeftTopBack = this.GetComponent<MeshFilter>().mesh.vertices[5];
        boxRightTopBack = this.GetComponent<MeshFilter>().mesh.vertices[9];
    }
    private void Update()
    {


    }
} 

These vectors in Box class is local Position. Then i want to access Box vertices from another script and convert vertice to world space:

private void AllocateSpace()
{
    Vector3 vector = transform.TransformPoint(packedBoxes[packedBoxes.Count - 1].GetComponent<Box>().boxRightBottomBack);
    Debug.Log(vector);
    pivotPoint = vector;
    Debug.Log(pivotPoint);
}

In Debug.Log i get same result, vector is not converted to world space. What i am doing wrong? Thank you.
