CMM Creo - Allow Assumptions not migrated to NX Align/Lock

CMM Creo - Allow Assumptions not migrated to NX Align/Lock This call needs to be transferred to GTAC US and marked as PR so that the customer data can be made available to the Milford migration lab people working with CMM Pro/E tools.

Please close this call as PR and upload the supplied data to the PR data tool.

Symptom / Problem DescriptionIn CREO there is an assembly constraint option "Allow Assumptions". The NX equivalent is constraint is "Align/Lock".

Currently the CREO constraint is migrated to NX "Align" instead of "Align/Lock".

Remark:

We always use Feature Translation Mode = BrepMode, however, in "FeatureMode" we get the same result.

For Assemblies Translation Mode we plan to use Feature Mode, however for CMM validation sometimes also Brep Mode is tested.

Environment setup:

CMM Solo 1847.192

NX 1859

Creo Parametric 4.0 - M080

Windows10

Expectations:

We expect the CREO "Allow Assumptions" constraint to be migrated to NX "Align/Lock" constraint

Example 1: "annahme_zulassen_01_01_teile.asm"

Creo: The Option "Allow Assumptions" ist active.

NX: The constraint is only "Align", but must be "Align/Lock", but must be "Align/Lock".

More Examples are documentated in the PDF in the PR data.
