First time I tried the same, but also I coped all vies (because the 
space between line and via must be check) and also I need to copy the 
components with pins, but not to copy component with pad because the 
space between pad and via on bottom layer may be 0.1mm, (the space 
between BGA pad and nearest via under BGA always 0.1mm) and separate the 
elements that must be copied and that must not, it is task...
