[zmwp3214]

I have made the following program but am unable to get it to switch to the file that is opened and then finish running the etransmit command in the newly opened file rather then when i switch back to the orginial drawing, i assume it is in the active drawing settings but cant figure out how to get it to change to the new drawing.
