Part iLogic yes, within an assembly no.

I have a part that currently triggers an external iLogic routine (simple alert box) on the On Open trigger.

What I DON'T want, is for this box to appear when an assembly that contains the part is opened.

What are my options?

Something like : 

If ThisApplication.ActiveDocument.DocumentType <> _
kPartDocumentObject Then 
	Return
End If

 that, at the top of the rule should work.

Thank you.  That worked perfectly.

I considered looking for something like this, but I assumed iLogic would be too myopic to see outside of the part that called it.
