NX11 cannot save weld points into TCM (Spot Weld Publishing is ON) where as in NX9 we allowed the customer to publish same spot welds.
Solution In NX9 we allowed the customer to publish spot welds even if they were in the retained state.
Retained state means that a link between the weld and the parent geometry was broken, possibly because the parent was no longer in the assembly.
When a weld gets published to TC a PSConnection object gets created and the NX links get recreated in TC as 'connected to' links. This allows the PSConnection object in TC to know who its parent parts are. This is critical for downstream manufacturing planning and accountability checks. This was an issue in NX9, So we fixed the issue and since NX10 would no longer allow a weld to be published into Tc if the links to the parent parts were broken(retained status). Since NX10 any welds published as Items need to have VALID 'connected to' part links in order to publish.
The proper workflow for Customer is to Import the welds using the same Import CSV command, then run the Connected Face Finder (this re-establishes the links) then save the file thus publishing the welds.
