Measuring GPS tolerance between two planes in Calypso

[[Ma...]]

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.

Features -> special features -> symmetry plane

 Don't you think you are suggesting symmetry planes too often?

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 )

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.

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.
