In the Copy window, we define the translation vector with the first and second points, in this case (0,0,0) and (0,0,10). Option Do extrude surfaces must be selected; this option allows us to create the lateral surfaces of the cube. Fill in the rest of variables as shown in the following image.
NOTE: In the Copy and Move windows, the button 
may be used to select existing points with the mouse, or alternatively enter its number in the entry field. 
NOTE: If we look at the Copy Window, we can see an option called Collapse. By activating this option, point 6 will be merged with point 5 when the entities are copied. By labeling the entities we could verify that only one point has been created.
If the user does not choose option Collapse, when the entities are copied (in this case from point 1 to point 5) GiD would create a new point (point 6) with the same coordinates as point 5.
To finish the copy command click Select, select the surface and then press ESC. We obtain the following surfaces:

Now select the volume to mesh and press ESC.
Then a window appears where the number of subdivisions for the volume limit lines should be entered.
Enter 10 and click Assign and select one of the lines in X axis, the parallel lines are also selected. Press ESC.
The same window appears again, click Assign and select one of the lines in Y axis, the parallel ones are also selected. Press ESC.
Again click Assign and select one of the lines in Z axis, the parallel ones are also selected. Press ESC.
Click Close when the window appears again.
Then, create again the mesh.
NOTE: GiD only allows the generation of structured meshes of 6-sided volumes.
