QUESTION How to make it a track surface

[Frank Alexandre]

Hi guys, trying to remove bumps from a track i got at this, with the border spline of the track. How can i fill it in 3ds Max?

By breaking two vertices, making one first and using cross i got this... almost there, but the end is not making it.

you can use "Cross Section" like this (about 9:20):
