Q:

Addition of line of latitude to a coordinate system

I need to know how to add a line of latitude to a graticule. I want to add a line of 66 deg. 34 minutes to north pole orthographic graticule. I am using ArcGIS

A:

I was able to accomplish this by creating a second graticule with the following settings:

I had actually set the Interval Y Axis to 66 degrees and 34 minutes but it added 60 seconds.  The result seems correct.
Similarly, I had set my own origin to 66 degrees and 34 minutes, but it changed it to 33 minutes and 60 seconds.  Again, the results are ok (I changed the colour to red for clarity).
