Placing markings

[joes1944]

When I copy and paste markings I use the Selection tool. Now the difficulty I'm having is placing and sizing the markings so that they are at equal places and sizes on both sides of the fuselage.

Place one marking, resize it. Also place it at one place at the fuselage.
Now duplicate the layer of that marking, so you got one with the same size.
Since the fuselage is often aligned pretty well, you can now get the copy of the marking at the good location by nudging it horizontally or vertically and you got them both at the same location.
