Unequally Disposed Zones (UZ) implemented?

[[Er...]]

Hello all,

I'm trying to improve agreement between optically scanned Zeiss Inspect (formerly known as GOM Inspect) and tactile Zeiss Calypso measurement results.

We currently have a lot of disagreement between HQ (using GOM) and local plants (using CMMs), might sound familiar to some of you.

Does anyone know if the most recent Calypso version has the UZ modifier implemented? We are currently using the 2023 version.

As far as i know - UZ for profiles are supported for a long time ( we have it on 2018 )

Question is where you want to impelement UZ ( i saw it on TP, but i doubt it's legal ) or if you argue about results differences between optical and tactile

The first thing I like to do when comparing Inspect to Calypso is to work with the same exact data set (export the raw points from Calypso and import them to Inspect). If the same exact data set nets vastly different results then there is an issue with the calculation. If it doesn't, then most likely your issue lies in the data collected from either the CMM or the Scanner. 

Having said that, Calypso has always been able to handle a UZ or an U tolerance on a Profile, but the legacy Profile was default setup for ASME, so you had to do some math to properly set it up for ISO. The new GD&T engine in 2025 can natively setup a UZ or U Profile depending on what standard you are working in.
