Thanks for confirming this. As a programmer (albeit old programmer!) it still surprises me after creating the extra gates in the SDK that there is so much complexity involved with linking to existing taxiway objects. I understand some of the reasons, but I feel that the lack of object inheritance is a real point of weakness in the SDK, especially in light of the rumor that Asobo is wanting to push more of the airport errors and corrections down to the end user community.
I’ll certainly give ADE a try to try and spare myself the time of redrawing the entire KCVX taxiway system.
