Fabrication Script for a Triangulated Form

Hi!

I might have missed good theads on it (I'm not a native speaker, sometimes I simply don't get the correct therms to search for.. any help appreciated!), or it might simply be that there aren't any:

I would like to develope a script that helps me mill the parts of a given (open or closed) mesh or polysurface consisting only of triangles.

It shall basically do a mesh-offset (with the material thickness to be fabricated in), giving me the geometry needed for milling - but all in single parts. Each geometry would be a single "truncated pyramid".

Are there any attempts at this already? It seems strange to me there are so many scripts dealing with waffle scripts, but not general other fabrication scripts (that I could find).

I though it should work out to determine which triangles have 2 of the same endpoints (-> they touch), building planes by 3pts of a surface, shifting them by the desired distance along their pendicular vector and intersecting them.

With 3 such lines from all sides, intersected with one another, I get the location of all the geometries points and can (somehow) assamble the final geometry for each part.. (?)

---

What I really don't know is how to set up the lists/data management to make it a script that can handle input by different geometries.. since they would have a different number of surfaces... but.. thats surely managable somehow ;)

And there will be more compex problems if the object has sharp corners, resulting the the errors you get also with an offset-mesh .. (the offset being thicker than the material allows on sharp edges).

Anyway - any help or ideas ahead?
