Hi,
I need to check in AutoLISP whether an attached Xref in the current drawing creates a circular reference (refers to itself or a parent Xref).
Is there a way, using AutoLISP or ActiveX, to detect this before attaching or reloading the Xref?
Ideally, a function that takes the Xref name and returns True/False for circular reference.
Any sample code or approach would be greatly appreciated.
