Topic: Overlay Or Attached Block Reference

[kwarmington]

How can I find out if a block has been overlayed or attached? It doesnt seem to be a property of the block Reference?

Cheers,

Kate

perhaps something like

if (btr.IsFromExternalReference || btr.IsFromOverlayReference)
{
   ed.WriteMessage("\nXref: true");
}

This may help ...

Thanks everyone, that worked a treat
