Syslog Extract:  n/a The problem where "CMM Report error in Max Deviation." has been investigated and the following has been found.

Siemens Digital Industries Software believes that the problem you reported where the CMM migration report shows 'Item Fidelity-Success' is working as intended since this migration report is reporting the results of the comparison method that is available through the "Check Feature Fidelity" command which is found within the "Migrated Item" tab in the "Displayed Part Properties" window (right mouse click on part in Assembly Navigator to get to this window). This "Check Feature Fidelity" command compares the "on Screen" body you see with the hidden body that was extracted from Source CAD and stored in the NX model and this comparison shows no diffs for this part.

As reported in this PR, the Compare Body found within "Analysis" in NX produces a difference in its results. However, this Compare Body uses extracted resultant geometry and so this is a different comparison from the one used by the "Check Feature Fidelity" command.
