I have a part with several slots called out. True position of the slot lenght and the width are dimensioned " true position .01 a,b,c for the width in this case .313 wide. Then the same for lenght. .371 long. 2021.2++ software. Programmed auto round slot the true position of the width and the lenght. but the slot lenght .371 comes out as the .313 so it is not adding the radius of each end of the slot in true position..... If I use distance adding radius the lenght of slot comes in correctly, so how do i get it to report the lenght with the radius of slot in true position for Lenght ... thanks
In the GeoTol (or are you using legacy?) dialog, you should have two options, either TP the width or the length of the slot. Make sure you have selected the correct feature for your tolerance.
i turned off legacy and found the true position of slot length or width as you discribed however it is still showing the slot length.. However it is showing the length as .311/.312 long . program shows it at the .371 long as programmed . i verified with calipers. also reverified my probe diameter is correct. so now how do i get the slot length to show correct? what could i have missed any idea??? Thank you

update... instead of auto slot i measured circle and circle.... construct slot... length measured better but still short. measurement .317 long.... could i be dealing with form of the slot causing the incorrect measurement??? calipers show slot length to be about .365 long. slot is short. however, cmm shows slot .317 long as I stated above. This part also has 2 other slots that are .313 wide by .500 long. The cmm is measuring those correctly to hard gage pin and caliper measurements. thanks
i figured it out.. hard to explain other than part is not symetrical. Flipped part and rechecked. pcdmis correct. operator not..... sorry for trouble... to much going on at same time.... again long story... thanks.
