This is a Python script for planning spheres in Dwarf Fortress. It assumes hollow spheres, with solid closed-corner walls and floors on all interior tiles.

This file requires Python 2.6 to run, and needs to be renamed to a .py file because DFFD doesn't allow .py files to be uploaded for some reason.

To change the size of the sphere, you need to edit the line "radius = 11" in the file to the desired radius of your sphere.
