Catia pattern information lost

CALL INFORMATION

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

Environment setup:

Catia V5 R21

NX 10.0.1.4

CMM 10.0.1.077

There seem to be two kind of patterns in Catia. In the first case (Muster1) the pattern in the assembly has only the constraints of the base component and all additional components are positioned according to the part pattern. This pattern information is stored on the assembly level. In the migrated NX assembly there are not pattern information available.

In a second case (Muster2) all pattern components are constraints to the corresponding hole. This case is migrated well to NX. However, pattern information is still lost.

In no case there are information in the CMM migration report about the missing/lost pattern information.

Example 1: Assembly called "Muster1" (Folder Muster_01)

o Pattern information is available in Catia assembly but not in NX

o CMM Report does not show any errors/issues about missing pattern information.

Catia

Base part is constraint to the corresponding hole. Other screw components are positioned according to the hole pattern in the Part1.

NX

No pattern information in the assembly and only the base part is constraint, all others are unconstraint.

When the Part1 in NX is moved only the base component stays on the correct position.

ADDITIONAL INFORMATION:

The reported issue behavior does not change whether parts are migrated in Feature oder BREP mode. The pattern information is lost in both modes.

EXPECTATIONS:

~~~~~~~~~~~~~

Please submit this to the migration lab for further investigations.

CMM is expected to migrate all pattern information from Catia to NX.

HOW TO REPRODUCE THE PROBELM:

Download the provided data file from GTAC (File: .zip)

o Migrate assemblies with CMM using default cmmOptions in BREP mode

o Inspect the resulting NX assembly and CMM migration report

o CMM migration report shows missing constraints.

SUPPORTING DATA: .zip

o	Worddoc with description and screenshots

o	Catia data

o	Migrated NX data

o	CMM Scratch Folders with logfiles
