Do you want the 'whole angle' or the 'half angle'?

Whole angle (angle from one side to the other) is the 'A' in the location reporting window.

Half angle (angle from one side to the centerline) is a bit more difficult.

F1         =GENERIC/CONE,DEPENDENT,RECT,OUT,$
            NOM/XYZ,0,0,0,$
            MEAS/XYZ,0,0,0,$
            NOM/IJK,0,0,1,$
            MEAS/IJK,0,0,1,$
            DISTANCE/0,0,$
            ANGLE/[COLOR="Red"]45,CON1.A/2[/COLOR]
DIM 1= LOCATION OF CONE F1  UNITS=IN ,$
GRAPH=OFF  TEXT=OFF  MULT=10.00  OUTPUT=BOTH
AX    MEAS      OUTTOL       DEV      NOMINAL     +TOL       -TOL    
A     45.0000     0.0000     0.0000    45.0000     0.0000     0.0000
END OF DIMENSION 1

where CON1 is the name of my cone and 45 is the nominal 'half angle'.
