Ok, that's doable - there are several ways:
1. Memblock-based objects
You can find various pieces of code where an object can be built to mimic a matrix.
The downsides are that they are slow to update (memblock to mesh to object) and that there can be several vertices in your object that map to the same point so that when you move one, you have to move all others are the same horizontal position. This makes it difficult and slow to change the height of a point, and the graphics card has to work harder to render your object (a 10x2 strip has 132 vertices).
2. Indexed objects
If you already know the sizes of your terrain, you can pre-generate them with welded vertices. Or you can use one of my utility plug-ins to generate them yourself (latest release, example code in the thread in my last post with code - wavy flag, has a generic routine to generate what you want)
The downside is that you need to write your own support code.
(Terrain built like this will have 33 vertices for a 10x2 strip).
