[To...] Posted February 11 Share Posted February 11 (edited) I have 2 inline cylinders with the following notation. Any thoughts on the lower tier? Di I create a position of cylinderC to cylinderD and then vice versa? I would have preferred to see each cylinder have a datum reference then use a positions of each cylinder to C-D but that is only wishful thinking.

[Ja...] Posted February 11 Share Posted February 11 If I am visualizing the inline cylinders you are describing correctly and your goal is to use a CMM and Calypso to measure this callout you may have some luck using the "Step Cylinder" function under "Features" - "Special Geometries" and that may take some of the guess work out of interpretation. That said I haven't played around with Step Cylinder too much so take my suggestion with a grain of salt. Link to comment Share on other sites More sharing options...
[Ri...] Posted February 11 Share Posted February 11 If they are supposed to be the same size, what I've done in the past is create a Max Inscribed Cylinder from all of the points, used that as the datum, and then evaluated the Position of the individual Cylinders back to that Max Inscribed Cylinder. If you are using the new GD&T you don't have to do this at all. This would just be a Sim Requirement. Link to comment Share on other sites More sharing options...

[To...] Posted February 12 Author Share Posted February 12 (edited) UPDATE Not sure if I asked the correct question. After re-reading the note, I don't know if they are including all 4 cylinders Edited February 12 Link to comment Share on other sites More sharing options...

[Ri...] Posted February 12 Share Posted February 12 Yeah. I think they are intending the top set to be evaluated separately from the bottom set. And yeah, looks like Step Cylinder it is. Link to comment Share on other sites More sharing options...
