I’m trying to model the brillouin zone of an FCC crystal, which is a truncated octahedron:
I want to visualize the octahedron inside the FCC structure made up of spheres.
I was hoping to find an easy way to place the planes between the spheres and then model their intersection as lines/cylinders.
Actually, while writing this post, I think I found a “manual solution” to my problem using the following 2 tricks:
1)Basically, I measure the distance between 2 spheres to get a line object between them.
2)Then I select the line and snap the cursor to its center (shift+S)
3)Then go to “User preferences” window, in the “Edit methods” tab, enable the “Align to view” button.
4)Select local axis system
5)Align view to selected
7)Rotate plane locally as needed (r-x-x, r-y-y or r-z-z with +/-90)
Now in principle I just need to add flat cubes instead of planes to be able to use booleans correctly for the intersection.
But if you know of any better way to get a line from 2 intersecting planes, faster ways to do it or any scripts which can help with modelling such things, please let me know.
