That plugin for adding elevation data....?

Thanks fellas, as you can see below in this case they were random points on a site so not bounded my a perimeter line.
Quite often I get spot levels given to me on a hardcopy of a plan so I want a simple way to turn elevation data into a reasonable terrain mesh.

so maybe you shouldn't focus on the perimeter; instead, build a set of 3d points (boundaries AND inside points)

i am not sure about the result with as few points as in your example

Thanks glro, that's what I've done.
