I'm trying to create a Spot Weld in CREO 2.0.  I've created the Datum Point... but I can't select it for my Location.

Dan,

Is that datum point is on surface? If datum point is not on surface, it will not select for location reference in spot weld.

I used the center of the locating nib.  I selected the round edge and selected "Center".

We have (2) .130 dia. embossed locating nibs that engage a couple of holes in the mating part.  I wanted to use the top, center of the nib.

Thanks for the response.  I'm not sure how to get the point where I want it...

I am having this same issue with Creo 5.0.5.

My datum point has been created in an assembly by intersecting two datum planes and an outer (top) surface of the weld. The two faces being welded together are coincident to one another.

What am I doing wrong?

I don't use the weld module.  However, from the other messages in this thread, It sounds like the datum point has to be "on surface" for it to be usable for the spot-weld feature.  Can you show the screenshot of how this point feature is defined?

 

I have a feeling that you have to have the point defined with this scheme (on surface, with 2 offset references):

The point is defined as the intersection of 2 datum planes and the surface on which the weld is to occur.

It is defined within the part in the attached image, but I have also defined it in the assembly itself and that did not change anything. I have also attempted defining each spot weld point as it's own point (in the model tree), rather than a point within a grouping with other points. This also did not change the behavior.
