[Ma...] Posted April 9 Share Posted April 9 Hello everybody, I have a design where there is a tolerance between two planes 20+-0.02 and GX tolerance of 0.02, How can I measure this in calypso? I have always associated these tolerance with Diameters and not the distance between two planes. Thank you and I will be waiting for your response.

GX and GN are signs of tangential evaluation - just like ASME. GX: maximum inscribed GN: minimum circumscribed For measuring that you can use cartesian distance, simple distance, caliper distance - just don't forget to select evaluation method ( can be set in feature - set globaly or in characteristic while selecting feature - applied localy ) Link to comment Share on other sites More sharing options...

Caliper distance, yes, maybe, but to a correct alignment which I'm sure is more mouse clicks to make than symmetry plane. Cartesian and other - absolutely not, because feature number 2 will delegate the tilt and center of gravity (or something similar) will be used from feature 1. There are possibly some older forum threads, including graphical explanation, but they are more difficult to find now after forum migration. 1 Link to comment Share on other sites More sharing options...

The proper way would be to use Symmetry Planes, but in theory there should be minimal difference between the Symmetry Plane width and a Cartesian Distance with the proper settings.

[Ma...] Posted Wednesday at 03:16 PM Author Share Posted Wednesday at 03:16 PM Hello everybody, I just did the tests using three different strategies, Cartesian, symmetry plane and Caliper distance. Caliper distance and Symmetry plane have similar results whereas cartesian gives very different result. I have tolerance of +-0.01, and the difference i have is 0.004 between cartesian and symmetry plane. Link to comment Share on other sites More sharing options...
[Ma...] Posted Wednesday at 03:21 PM Share Posted Wednesday at 03:21 PM Cartesian distance is not depending on alignment. Caliper does and symmetry plane averages both planes. Link to comment Share on other sites More sharing options...
[Ji...] Posted Thursday at 06:16 AM Share Posted Thursday at 06:16 AM Is it GX or SX(SN) between two planes? Link to comment Share on other sites More sharing options...
[Ma...] Posted Thursday at 09:38 AM Author Share Posted Thursday at 09:38 AM Please sign in to view this quote. It is GX in this case Link to comment Share on other sites More sharing options...

Yes, The objective of GX was to guarantee in assembly that, the counter parts that assembles on top of it, do not exceed and come out. With the symmetry plane and evaluation method, I think it exactly, does what is required. Link to comment Share on other sites More sharing options...
