Good morning.
 
I've been spending some time thinking about the north arrow we use on our plans, somewhat dissatisfied with the standard north arrows available in AutoCAD.
 
Happened upon a description of the compass rose, and enjoyed reading the description of the compass rose http://en.wikipedia.org/wiki/Compass_rose
 
In particular, I very much enjoyed the aesthetic quality of the 32-point compass rose by Aguiar (Portugal, 1492):

So much so, that I've drafted the same (with some alterations) in AutoCAD, which I'm freely offering to any of you if you wish to use:
 
 
I'm also wondering whether any of you might have a comment on a particular part of the wikipedia article:
"The contemporary compass rose appears as two rings, one smaller and set inside the other. The outside ring denotes true cardinal directions while the smaller inside ring denotes magnetic cardinal directions".
 
I am contemplating using this north arrow on our plans. I have rotated the inner ring by 13.5 degrees, the approximate local variation for Great Barrington, MA.
 
Although most plans in this area are still filed with reference to a historic field magnetic datum (and the deeds obviously reflect this practice), there are increasingly beneficial uses for reference to state plane coordinates, including new requirements of the MA Land Court, and integration with MassGIS and other efforts to catalog land information.
 
Therefore, in thinking about the use of this north arrow, I am most inclined to orient the major axis of the north arrow to MA State Plane Coordinates.
 
Any comments or suggestions would be appreciated.
