Importing Layer Filters into multiple drawings

[Sterling2017]

Thanks Tom. Sounds like its a problem to be solved in later versions perhaps.
Yes, have audited and recovered due to the crashing problems. No beans.
I don't see how you avoid those layer filters - they are automatically put into the list and you can't select which ones to import/export.
Thanks

First from a drawing without any Xrefs or the offending Layer Filters run LayerSaveFilterTree so LayerLoadFilterTree cannot create these issues again.
Set UCS to World first and try the Entire drawing option of WBLOCK command.
or insert the drawing into a blank one.
or use the FILTERS command to select ones for deleting.

Running this lisp will remove all Layer Filters. Toggle the Layer Palette off then back on to update it's display.

Thanks for the Lisp, that's helpful. I had also made a filter from one of our blank templates, essentially the same.
I have having success in other files loading these filters (just quick test files). Its just that first file which has a duplicate of "All non-Xref Layers" which cant be removed even with that LISP routine and crashes if I click on one of those duplicates.
Well, I think this might be an anomaly, working in other files and found some new solutions to work with. Ill just work around it for now within this file.
Thanks for the help!

For removing things like that I've had luck with saving the file as a DXF, opening it in a ascii text editor and searching for "All non-Xref Layers". You would need to get somewhat familiar with DXF format to tell which parts to remove, but as long as you change the name so the original file isn't going to get overwritten even partially deleting the Layer filter should be enough for AUDIT to finish cleaning it up.

Really is something AutoCAD's staff needs to fix.
