[Wi...] Posted January 23, 2020 Share Posted January 23, 2020 Why do i show a .00505 difference when i offset exactly 1.8558......drives me nutsWHY.JPG Link to comment https://qualityforum.zeiss.com/topic/16594-plane-with-offset/ Share on other sites More sharing options...
[To...] Posted January 23, 2020 Share Posted January 23, 2020 The Y value you're seeing originates from the origin of the plane which is likely in the lower left corner of your plane. You have some deviation in the A1 and A2 values meaning your plane is tilted a little bit from the Y axis. So, in reality, the mid-point fo the plane is probably atY0. You can test this using a point feature and recalling the plane, you would probably see the correct y value.

[Wi...] Posted January 23, 2020 Author Share Posted January 23, 2020 Thanks Tom..... I did just what you said.... use the point feature and recalled it into the offset plane... My zero is zero 🙂point_feature.JPGbase.JPG Link to comment https://qualityforum.zeiss.com/topic/16594-plane-with-offset/#findComment-92526 Share on other sites More sharing options...
[To...] Posted January 23, 2020 Share Posted January 23, 2020 Please sign in to view this quote. The Base Alignment would have worked fine with the offset plane. I just suggested the point so you could see that I wasn't making stuff up. lol Link to comment https://qualityforum.zeiss.com/topic/16594-plane-with-offset/#findComment-92528 Share on other sites More sharing options...
[Wi...] Posted January 23, 2020 Author Share Posted January 23, 2020 i didnt trust it with it showing nominal at 0 but the actual at .005".... guess im a little anal about some stuff....

The zero point will be where all three planes intersect. Link to comment https://qualityforum.zeiss.com/topic/16594-plane-with-offset/#findComment-92532 Share on other sites More sharing options...

[Wi...] Posted February 6, 2020 Author Share Posted February 6, 2020 I noticed that with a sym plane i was using for bonus. I could use 2 space points and get a true pos of .002" but couldnt get bonus... when i used the sym plane i would get .02"... crazy right ? calypso was automatically projecting it up to my trihedron. I had to adjust the projection and that fixed it up. Link to comment https://qualityforum.zeiss.com/topic/16594-plane-with-offset/#findComment-92536 Share on other sites More sharing options...
