I am making an addon for an aera, and I am adding roads using the taxiways in AFCAD. I have got the taxiways(roads) to look just like roads, but that isnt my problem. There is a highway that goes alonside a cliff, and whenever I cover it with the taxiway in AFCAD it flattens the hill. The airport is PAHN (Haines, Alaska). You would notice the road I am talking about right away if you went to that airport.
Is there a way to make the taxiway follow the ground level?
If Not it will work like this, but I am trying to get the aera as real as possible.

Also I am using AFCAD 2.21 so if there is a newer version I would appreciate a link.
Thanks a lot,
