3 8mm holes on -A- surface, one of which is -C-. -B- is 12.7mm hole on another surface.
The feature control frame calls out the other 2 8mm holes @ TP .5 max material to -C- only...no other datum callout in the frame.
In my program, I make -C- my xyz zero, but leave my alignment alone since theres no alignment stated in the FCFrame and measure and tolerance the 2 holes to the .5mm TP.
Does this sound right....reason I'm asking is the gage shows the holes to be good (to themselves...pattern check) yet the program is showing them to be way off.
