Need help reporting Taper/foot of a Cone

Question

Hey guys. I am inspecting a part with a tapered bore. The drawing calls out '1.5" PER FOOT TAPER' with a tolerance block tolerance of ±.010. I measured the feature as a cone and my options are to report as an angle or half angle. I know that the half angle should be 3.5763. And to translate that to taper per foot I worked out the following equation: taper/foot = 24*tan(half angle). How can I implement this so that my report shows the measured taper/foot with a nominal of 1.500 ±.010? Currently I am reporting the half angle with a tolerance of ±.0238 which is what I calculated as .010"/foot taper as a half angle. Appreciate the help.

How about you construct a circle 12" from the cone apex and report the diameter?

That can work, instead of putting "Taper" and "V2" in there, create an assign statement before the Key-in, and just hit "Create" on the popup, the fields will display the actual number values. The report will as well. I just hard types values, but you'd change the Variables to your formulas. Your TAPER="CON2" will just display the text CON2. I think you're wanting 
 TAPER = CON2.TA/2 or just put in 1.500 since that is the nominal. 
 V1 = CON2.A/2 
 ASSIGN/NOM_TAPER=1.5
 ASSIGN/MEAS_TAPER=1.495
DIM TAPER= KEYED IN DIMENSION OUTPUT=BOTH
AX MEAS NOMINAL +TOL -TOL DEV OUTTOL
M MEAS_TAPER NOM_TAPER 0.0100 0.0100 -0.0050 0.0000 --#------

WilliamL beat me to it. As he said, it is built right into the circle construction.
