Re-orienting surfaces or building a surface on a tilted angle

[iskanderani.m (Mohanned Iskanderani)]

Hello Grasshopper Community,

I am trying to make surfaces half way through pyramid shapes to trim the tips. The points are there, tetrahedrons are there too, but no idea how to rotate or build a surfaces on those planes.

I tried a couple of different tools and stuff but didn’t work out well for me.

PS: I am using Lunchbox in that script.
