Is there a way using AFCAD to place an "X" at each end of a taxiway to show that it's closed, like you can do with a runway?

Under the taxiway properties, select 'link type' and pick closed.

I did that, but the X doesn't actually appear on the taxiway in the game. It just appears in AFCAD.

Never seen any X:es on the ground on closed taxiways.Usually they are marked with a traffic stopbar and red lights.Bjorn

I did not have any trouble

That's a runway, not a taxiway.

Whoops

NP - easy to get confused.
