Instead of using the hidden (why is it hidden) "sn" option to center the grid,
consider using DTI's Space and Ceiling command. It is part of a free package that you
can download from the internet. We prefer this command over the built-in commands for
creating ceilings. It centers the grid, works very fast, and you can select multiple
spaces at one.
I don't remember the exact name of the website right now, but maybe you can search on
the internet for "DTI Productivity Pack". It contains some other very useful features
such as Wall Fillet, and auto-layering for text, dimensions and leaders.
