Topography Model, Layered and Laser Cut

Hi,

I'm a 5th year Architecture Student and working on creating 2.4m x 1.2m Topography model for our site at a scale of 1:500. I really love grasshopper however am still quite inexperienced with it but am trying to force myself to use it in all my projects so I can learn a little more each time.

I was lucky enough to get hold of a set of points depicting the site topography which have around 60m variance throughout the site, and have used this to generate a mesh giving me a surface. What i'd like to do is use this to create a load of layers trimmed to the mesh, then lay them out and number then so I can nest them and laser cut them.

I have seen plenty of waffle but I need to do this in a horizontal only layers which stack and i'm not entirely sure how to approach this. So far I created a bounding box and then measured the distance between the top and the bottom point to subdivide into the thickness of the material I have but then I became stuck, any help would be greatly appreciated.

Thank you for your time,

Richard.
