[Me...] Posted October 18, 2019 Share Posted October 18, 2019 Hi all, I have a true position dimension with the datum structure being an axis between two circles. |TP|Ø0.010|R-X| I create the TP characteristic just as on the print but I don't get an answer or i get zero as an answer. The feature in question is on the theoretical same axis as the datum. Am I getting zero simply because with the datum structure can run along the same axis infinitely until it fits perfectly on the circle? I get variation in the feature X and Z position so I know its not really perfect. I need an explanation to bring to the engineer if it is linked to my assumption. Thanks, JG Link to comment Share on other sites More sharing options...

[Me...] Posted October 18, 2019 Author Share Posted October 18, 2019 Here is a pic. I cannot post a pic of the CAD/Print due to NDA... blue 3d line at the bottom left is the Axis Datum between Datum X-R Thanks, JGTP axis pic.PNG Link to comment Share on other sites More sharing options...
[Me...] Posted October 19, 2019 Author Share Posted October 19, 2019 Re-generate the same elements with which you created your alignment and check the true position with the new elements. You could also check the concentricity as a support to see if they are actually zero. Link to comment Share on other sites More sharing options...
[Me...] Posted October 21, 2019 Author Share Posted October 21, 2019 So I figured it out... It must have been a bug in the version I was using. I installed the new service pack and now I have a reasonable answer that's not zero. Link to comment Share on other sites More sharing options...
