I agree it's better to place a mark on one of the layers which will not be
printed.
Exactly which layer is another issue; for example I wouldn't use the
Courtyard
Layer since in the future someone may want to implement formal collision
tests
on Courtyard outlines. There are also any number of ways to accomplish the
goal - for example you can place a small target mark on the Silk Layer and
that
serves as a placement reference for a generic mechanical model, or you can
put a target mark as well as an outline box to show the actual mechanical
extent
of a specific mechanical component.
