Problem Description:

================================

CMM - Handling of circular references in ProE .

Circular references are sometimes part of design. CMM handles various circular references in different way, but the most common behavior is that NX dataset is created, but has no geometry.

Sometimes it even crashes or runs in loop indefinitely.

Application project: CMM PROE to NX

Assembly: BOM structure

Common/Part specific: common

Function: circular references in ProE BOM structure

=============================================================================

Versions:

================================

NX: 8.5.2.3

Work Around:

================================

Unknown

Steps to Duplicate:

================================

1. Use attached data to load part A5E00128300.prt to ProE WF3 and save it to Teamcenter. Please note, that the given part is referenced to an assembly, which is referenced by the same part again.

See attached MS Word file for steps to duplicate and for clarification.

==> ERROR:

================================

CMM hangs

Expectation:

================================

Problem is part specific: no

Platform: Intel Win764-bit

Problem verified on the following platforms and OS versions:

Intel Win764-bit, NX8.5.2.3

Additional Notes:

================================

Circular references are errors in design, which takes time to identify, remove and repair in CMM migration process. With proper handling, these errors would have cost us much less time, effort and resources. The problem where "CMM Handling of circular references in ProE" has been investigated and the following has been found.We have not been able to reproduce this issue. We have not received a response to our request for more information on how to reproduce this. When we receive this information we will consider this enhancement request.
