cyclic assembly structure
cyclic assembly structure
(OP)
A coworker ran across a file that will not open, but gives an error "Attempt to load a cyclic assembly structure". It should be a single part in the file and not an assembly, but who knows how it has been abused.
Any tricks to get this to open so we can fix it? Or is this a case for GTAC?

To an Engineer, the glass is twice as big as it needs to be.

RE: cyclic assembly structure
(the following assumes non-managed NX .a.k.a native mode)
"%UGII_BASE_DIR%ugii\ugpc.exe" -a interesting_part.prt may help shed some light on the situation. It will output the as-save assembly structure which may help understand the issue. It may be that the aprt had been given a component and that independently (in a different NX session) that component had been added and be given the top assembly as a child.
Also, were there any recent changes to the customer defaults made in the area of version rules? If changes have been made part names that had previously been cosidered unique by NX could now be seen as being versions of the same part number. (it's a long shot but worth mentioning)
(end-of-unmanaged-asumption)
Was the value of the environment variable UGII_OPTION changed?
Looking at the NX log file may also give details which may point at which files are in the "chain" that causes the circularity.

When and if you exhaust all possibilities then you may still need help from GTAC, but you'll probably either fix it yourself ahead of time or at least identify something more specific for them to solve.

I am currently running in native mode. I tried ugpc.exe and it ran for about 10 minutes but produced no output that I could find. I tried a few different combinations of command line options all with the same result.
Thanks to all for your suggestions. Looks like a job for GTAC.

import the corrupt file into a new part.
