plane to plane error
i was measuring an oring groove that by calipers measured 0.645 the arm measured a plane to plane measurment of 0.234 i measured a plane at the top of the groove and a plane at the bottom of the groove and measured the distance between the two in 3d and that is number i got however all other dimensions i took using the same set up and alignment came out correct .
Are you sure that all of the hits were "GOOD"?
One way to trouble shoot this is to report out the location of both planes.
The difference between the 2 should equal the distance you are looking for.
Also, report out the flatness of each of those planes. That will help you see if you are getting bad hits.
And if you apply graphical and textual analysis to the flatness dimensions, that will also help out.

that is what i thought as well so redid this about 6 times and got the same number with in a couple thousandths each time and redid calibration and checked the arm using the bar and sphere and redid and got the same results the strange thing is that all the other measurments i took came out right.
What is the result when you report out the plane locations separately?

what? how do you mean i am sorry i am very new to this and not sure what you mean i measured a plane at the top of the oring groove and one at the bottom of the groove and then used the dimension between butttom on the screen the you know the arrow between two lines and kept gettting the same thing no matter what i did i am sorry about about my ignorance but i am trying
You can dimension each plane separately.Originally Posted by QCINSP38
If the distance you want is in the Z axis, just dimension each plane in Z.
Or you could just look at the "actual" Z values in the measured feature's listing.
Of course, if the planes are not normal to any axis, this will not work.

Ok i wish i could do that but the parts are gone now i will keep this mind so that when it happens again and i am sure it will based on my limited expierence i am sure it was something i did wrong , i just dont know i appreiate your help and time thank you !
If you saved the program after the last part measured you can still check those plane locations.

really i did not know this? i will go and check this thank you very much
Do you have to pick 3D then check the shortest distance box ? We had a similar problem and that seemed to have fixed it.
