How to make terrain walls

Hello,

I’m trying to make a boat port, the problem is that with the brush for the height of the terrain, it is impossible to make a completely vertical cut in the terrain.

Would be perfect is a completely vertical terrain reduction, like a terrain wall, anyone know how do it?

Thanks!

You can’t, because then you would need 2 points on the terrain with same x,z and different y values.

This is not possible since terrain is a grid of unique x/z pairs with a height of y.
