Thanks @skunks , as always a great example.
Also, they are treated as beams, and most of the measures you would need are automatically included.
Use result items like:
Quantity:
Beam Resultant
Stress : Beam Tensile...etc
Failure Index (Spot weld material has failure criteria)
Display Location:
Beams (If you only want to show the spot welds)
---------------------------
I have used imported weld point data (tabulated text.pts) to create many spot welds automatically. Only one point needs to be defined and Creo will project to find the intersections to the shell quilts. If you can imagine putting all the welds on a car door from inner to outer sheet metal, an automatic process is pretty useful. This was my only use case for welds and modal analysis was used so I don't know much about analyzing weld quality / stress / failure.
