Measuring hole on curved Surface

I have no Cad model and I need to measure a Hole on a curved surface, how do I go about this??

Parents

Measure a .250 hole in a 5.00 tube.

TUBE LIES IN Y-AXIS
TUBE DIAMETER = 5.00
ID HOLE DIAMETER = 0.250
MEASURE ID HOLE CCW
NUMBER OF HITS = 8
MEASURE DEPTH = 0.037
TUBE WALL THICKNESS = 0.074

Tube is properly fixtured and aligned.
.250 hole is facing upwards.

Generic cylinders are just for graphics screen view.

ASSIGN/NUMHITS = 8
ASSIGN/ANG = 0
ASSIGN/ANG_INC = 360/NUMHITS

ASSIGN/HOLE_D = 0.250
ASSIGN/RAD1 = HOLE_D/2
ASSIGN/TUBE_D = 5.00

ASSIGN/MEASURE_DEPTH = 0.037
ASSIGN/RAD2 = TUBE_D/2 - (MEASURE_DEPTH)
ASSIGN/TUBE_WALL_THICKNESS = 0.074  

ASSIGN/XVAL = RAD1*COS(DEG2RAD(ANG))
ASSIGN/YVAL = RAD1*SIN(DEG2RAD(ANG))
ASSIGN/ZVAL = SQRT((RAD2^2) - (RAD1*COS(DEG2RAD(ANG))^2))  

ASSIGN/IVEC = COS(DEG2RAD(ANG))
ASSIGN/JVEC = SIN(DEG2RAD(ANG))
ASSIGN/KVEC = 0
