Find rotation of viewcube/coordinate plane in AutoLISP

[davidlanesmith673]

On my AutoCAD drawing, the coordinate plane is rotated, and I was wondering if there is a way to find that rotation using AutoLISP.

(cvunit (angle '(0 0) (getvar 'ucsxdir)) "radian" "degree")

I think the UCSXDIR System Variable would be applicable if it was the User Coordinate System that's rotated, but if that were the case, you would not see the little box at the axis intersection, which indicates that you're still in the World CS, and the appearance of the icon is from a twisted view, not a rotated UCS.  I think you want the VIEWTWIST System Variable, which will tell you the angle directly, using your current angular units mode and precision.

Finding the VIEWTWIST system variable worked. I tried the first suggestion, but it just returned 0.
