Solved: Re: Creo 2 Model Tree Icon?

MikeMarcoux · ‎Jul 23, 2015

I've run into a model tree icon that I've never seen before. It looks like a graph icon, but it's yellow. Does anyone have an idea of what this is, and what feature it represents?

You can check if there are relations that depend on these graphs by opening up Tools->Relations dialog box, selecting "Section" in the "Look In" field and then selecting the sweep.

You might see something like sd6=EVALGRAPH ("GRAPH_3", TRAJPAR * 360)

It seems Creo Parametric does not keeps track of the parent/child relationship when it comes to graphs. I have a part where I can change the graph which drives a sweep section and nothing changes - it will not be updated until you "edit definition" of the sweep feature and then exit (without making any real changes).

worse, if you delete the graph, the sweep will remain, but who knows when things will start to fail?

those are datum graph features.

They're probably being used by that last sweep in your tree to vary the dimensions of the sweep cross-section according to the graph profiles.

That's what I thought Paul, but they don't seem to be referenced by it. They have no child or parent listed. When I interrogate the feature, it's says that they are a "graph".

Wow. How odd. There are no relations in the sections drop down either. I was wondering why nothing failed when I deleted the graphs either. This must explain it. How very odd indeed.
