Problem with corridor surface

[jonathan36LP7]

Does anyone here encounter this in Civil 3D? I made a corridor surface but in perspective view, there is a long line from the top of the surface to the bottom.

Hi jonathan36LP7,

This is known as corridor waterfall. Extend you profile up to ends of the alignment.

Here is how to solve it.
