Terraforming via taxiways

Hi guys!

It would be nice if the taxipaths would be able to terraform. The taxiwaypoints should give the altitude on both ends and the taxipath width should give the width of the terraforming.

Airports are rarely flat. The different aprons are usually on different altitude and taxiways are usually steep in one of the direction. If we could flatten the aprons and the connecting taxiways could get a slope according to the taxipoints altitude we could make really good terraforming and sloped taxiways.

I know there are rectangles and runways with profiles and flattened aprons but to blend them to each other is really hard.

Any thoughts?
