Sorry, this has nothing to do with Dynamic blocks, but I can't make head or tail out of Autodesk's new structure...
I'm having a senior moment. When you substiture one xref with another, the reference retains the name of the original xref. However, there's a simple trick to update that reference to the new name - but I've forgotten it.
Help!
Change the saved path of Xref and change the name of xref?
Easiest way I know...
I know that's simple enough but (and memory may be failing me) I'm sure that there's a command whose 'side effect' does the same thing
Nothing I'm aware of..
Check help for Xref-related commands.
