Seems like a perfect task for a SKILL routine. Perhaps something like, 1) draw a box around whatall you want flipped 2) right-click to close the box 3) select from a list of choices "top->bottom" "bottom->top" "cancel" The routine would snip any etch that crossed the boundaries of the box. One subtlety: would you be wanting what gets flipped to then be deleted from their original locations or not? An interesting idea. Good enuff for a paper at the ICU perhaps?
