Yellow "TBD" symbol

[cmorel]

Hello,

I have stumbled across a random symbol that had appeared next to the "stop light" and I am unable to find anyone who knows what it is and I'm hoping someone on here can help. When I opened my model today a yellow circle with "TBD" in it popped up next to my stop light. The strange part is I have a a green light so it doesn't appear that there are any failed parts or features. Does anyone know what this is and how I get rid of it? If it is relevant, I'm working in Creo 2.0.

Here is a screen shot:

Thanks for your help.

TBD next to green light

Yellow TBD button appears to indicate that an external reference is not available or updated within the assembly or part model

• Displays at the highest level within assembly structure

Thanks for letting me know what this is! Can you suggest how to find the external reference? When I perform a model check I do not find any external or circular references.

We use a lot of merged models and external merges. That is usually where we have problems regeneration issues.

I can't specifically remember if that is where I saw the yellow TBD though, it's been a while since I've noticed show that.
