Have been working with a default airport trying to get it a little more accurate. Having a problem with one taxiway that joins the runway. The default joins the runway as shown in the picture. Only one side curves into the runway and the taxi lines only go one way. I have been trying to get it curved on both sides with the taxi lines going both ways. I have checked the manual and looked at some default airports where the taxiway joins curved on both sides and cannot see where anything is different than I have done. I must be missing something simple.
